53 * DOC: Station handling
54 *
55 * Stations are added per interface, but a special case exists with VLAN
56 * interfaces. When a station is bound to an AP interface, it may be moved
57 * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
58 * The station is still assumed to belong to the AP interface it was added
59 * to.
60 *
61 * Station handling varies per interface type and depending on the driver's
62 * capabilities.
63 *
64 * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
65 * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
66 *  - a setup station entry is added, not yet authorized, without any rate
67 *    or capability information, this just exists to avoid race conditions
68 *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
69 *    to add rate and capability information to the station and at the same
70 *    time mark it authorized.
71 *  - %NL80211_TDLS_ENABLE_LINK is then used
72 *  - after this, the only valid operation is to remove it by tearing down
73 *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)
74 *
75 * TODO: need more info for other interface types

78/**
79 * DOC: Frame transmission/registration support
80 *
81 * Frame transmission and registration support exists to allow userspace
82 * management entities such as wpa_supplicant react to management frames
83 * that are not being handled by the kernel. This includes, for example,
84 * certain classes of action frames that cannot be handled in the kernel
85 * for various reasons.
86 *
87 * Frame registration is done on a per-interface basis and registrations
88 * cannot be removed other than by closing the socket. It is possible to
89 * specify a registration filter to register, for example, only for a
90 * certain type of action frame. In particular with action frames, those
91 * that userspace registers for will not be returned as unhandled by the
92 * driver, so that the registered application has to take responsibility
93 * for doing that.
94 *
95 * The type of frame that can be registered for is also dependent on the
96 * driver and interface type. The frame types are advertised in wiphy
97 * attributes so applications know what to expect.
98 *
99 * NOTE: When an interface changes type while registrations are active,
100 *       these registrations are ignored until the interface type is
101 *       changed again. This means that changing the interface type can
102 *       lead to a situation that couldn't otherwise be produced, but
103 *       any such registrations will be dormant in the sense that they
104 *       will not be serviced, i.e. they will not receive any frames.
105 *
106 * Frame transmission allows userspace to send for example the required
107 * responses to action frames. It is subject to some sanity checking,
108 * but many frames can be transmitted. When a frame was transmitted, its
109 * status is indicated to the sending socket.
110 *
111 * For more technical details, see the corresponding command descriptions
112 * below.

115/**
116 * DOC: Virtual interface / concurrency capabilities
117 *
118 * Some devices are able to operate with virtual MACs, they can have
119 * more than one virtual interface. The capability handling for this
120 * is a bit complex though, as there may be a number of restrictions
121 * on the types of concurrency that are supported.
122 *
123 * To start with, each device supports the interface types listed in
124 * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
125 * types there no concurrency is implied.
126 *
127 * Once concurrency is desired, more attributes must be observed:
128 * To start with, since some interface types are purely managed in
129 * software, like the AP-VLAN type in mac80211 for example, there's
130 * an additional list of these, they can be added at any time and
131 * are only restricted by some semantic restrictions (e.g. AP-VLAN
132 * cannot be added without a corresponding AP interface). This list
133 * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
134 *
135 * Further, the list of supported combinations is exported. This is
136 * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
137 * it exports a list of "groups", and at any point in time the
138 * interfaces that are currently active must fall into any one of
139 * the advertised groups. Within each group, there are restrictions
140 * on the number of interfaces of different types that are supported
141 * and also the number of different channels, along with potentially
142 * some other restrictions. See &enum nl80211_if_combination_attrs.
143 *
144 * All together, these attributes define the concurrency of virtual
145 * interfaces that a given device supports.

148/**
149 * DOC: packet coalesce support
150 *
151 * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
152 * packets does not do anything with these packets. Therefore the
153 * reception of these unwanted packets causes unnecessary processing
154 * and power consumption.
155 *
156 * Packet coalesce feature helps to reduce number of received interrupts
157 * to host by buffering these packets in firmware/hardware for some
158 * predefined time. Received interrupt will be generated when one of the
159 * following events occur.
160 * a) Expiration of hardware timer whose expiration time is set to maximum
161 * coalescing delay of matching coalesce rule.
162 * b) Coalescing buffer in hardware reaches it's limit.
163 * c) Packet doesn't match any of the configured coalesce rules.
164 *
165 * User needs to configure following parameters for creating a coalesce
166 * rule.
167 * a) Maximum coalescing delay
168 * b) List of packet patterns which needs to be matched
169 * c) Condition for coalescence. pattern 'match' or 'no match'
170 * Multiple such rules can be created.

276 *	has a private regulatory domain, it will be returned. Otherwise, the
277 *	global regdomain will be returned.
278 *	A device will have a private regulatory domain if it uses the
279 *	regulatory_hint() API. Even when a private regdomain is used the channel
280 *	information will still be mended according to further hints from
281 *	the regulatory core to help with compliance. A dump version of this API
282 *	is now available which will returns the global regdomain as well as

284 *	If a wiphy is self-managed (%NL80211_ATTR_WIPHY_SELF_MANAGED_REG), then
285 *	its private regdomain is the only valid one for it. The regulatory
286 *	core is not used to help with compliance in this case.
287 * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
288 *	after being queried by the kernel. CRDA replies by sending a regulatory
289 *	domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
290 *	current alpha2 if it found a match. It also provides
291 * 	NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
292 * 	regulatory rule is a nested set of attributes  given by
293 * 	%NL80211_ATTR_REG_RULE_FREQ_[START|END] and
294 * 	%NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by
295 * 	%NL80211_ATTR_REG_RULE_POWER_MAX_ANT_GAIN and
296 * 	%NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
297 * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
298 * 	to the specified ISO/IEC 3166-1 alpha2 country code. The core will
299 * 	store this as a valid request and then query userspace for it.
300 *
301 * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
302 *	interface identified by %NL80211_ATTR_IFINDEX
303 *
304 * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
305 *      interface identified by %NL80211_ATTR_IFINDEX
306 *
307 * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
308 *	interface is identified with %NL80211_ATTR_IFINDEX and the management
309 *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
310 *	added to the end of the specified management frame is specified with
311 *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
312 *	added to all specified management frames generated by
313 *	kernel/firmware/driver.
314 *	Note: This command has been removed and it is only reserved at this
315 *	point to avoid re-using existing command number. The functionality this
316 *	command was planned for has been provided with cleaner design with the
317 *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
318 *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
319 *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
320 *
321 * @NL80211_CMD_GET_SCAN: get scan results
322 * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
323 *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
324 *	probe requests at CCK rate or not.
325 * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
326 *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
327 * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
328 *	partial scan results may be available
329 *
330 * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
331 *	intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
332 *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
333 *	are passed, they are used in the probe requests.  For
334 *	broadcast, a broadcast SSID must be passed (ie. an empty
335 *	string).  If no SSID is passed, no probe requests are sent and
336 *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
337 *	if passed, define which channels should be scanned; if not
338 *	passed, all channels allowed for the current regulatory domain
339 *	are used.  Extra IEs can also be passed from the userspace by
340 *	using the %NL80211_ATTR_IE attribute.  The first cycle of the
341 *	scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
342 *	is supplied.
343 * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
344 *	scheduled scan is not running. The caller may assume that as soon
345 *	as the call returns, it is safe to start a new scheduled scan again.
346 * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
347 *	results available.
348 * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
349 *	stopped.  The driver may issue this event at any time during a
350 *	scheduled scan.  One reason for stopping the scan is if the hardware
351 *	does not support starting an association or a normal scan while running
352 *	a scheduled scan.  This event is also sent when the
353 *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
354 *	is brought down while a scheduled scan was running.
355 *
356 * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
357 *      or noise level
358 * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
359 *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
360 *
361 * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
362 *	(for the BSSID) and %NL80211_ATTR_PMKID.
363 * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC

365 * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
366 *
367 * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
368 * 	has been changed and provides details of the request information
369 * 	that caused the change such as who initiated the regulatory request
370 * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
371 * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
372 * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
373 * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
374 * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
375 * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
376 * 	to (%NL80211_ATTR_REG_ALPHA2).
377 * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
378 * 	has been found while world roaming thus enabling active scan or
379 * 	any mode of operation that initiates TX (beacons) on a channel
380 * 	where we would not have been able to do either before. As an example
381 * 	if you are world roaming (regulatory domain set to world or if your
382 * 	driver is using a custom world roaming regulatory domain) and while
383 * 	doing a passive scan on the 5 GHz band you find an AP there (if not
384 * 	on a DFS channel) you will now be able to actively scan for that AP
385 * 	or use AP mode on your card on that same channel. Note that this will
386 * 	never be used for channels 1-11 on the 2 GHz band as they are always
387 * 	enabled world wide. This beacon hint is only sent if your device had
388 * 	either disabled active scanning or beaconing on a channel. We send to
389 * 	userspace the wiphy on which we removed a restriction from
390 * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
391 * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
392 * 	the beacon hint was processed.
393 *
394 * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
395 *	This command is used both as a command (request to authenticate) and
396 *	as an event on the "mlme" multicast group indicating completion of the
397 *	authentication process.
398 *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
399 *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
400 *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
401 *	the SSID (mainly for association, but is included in authentication
402 *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
403 *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
404 *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
405 *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
406 *	to be added to the frame.
407 *	When used as an event, this reports reception of an Authentication
408 *	frame in station and IBSS modes when the local MLME processed the
409 *	frame, i.e., it was for the local STA and was received in correct
410 *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
411 *	MLME SAP interface (kernel providing MLME, userspace SME). The
412 *	included %NL80211_ATTR_FRAME attribute contains the management frame
413 *	(including both the header and frame body, but not FCS). This event is
414 *	also used to indicate if the authentication attempt timed out. In that
415 *	case the %NL80211_ATTR_FRAME attribute is replaced with a
416 *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
417 *	pending authentication timed out).
418 * @NL80211_CMD_ASSOCIATE: association request and notification; like
419 *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
420 *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
421 *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
422 * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
423 *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
424 *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
425 *	primitives).
426 * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
427 *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
428 *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
429 *
430 * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
431 *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
432 *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
433 *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
434 *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
435 *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
436 *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
437 *
438 * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
439 *	FREQ attribute (for the initial frequency if no peer can be found)
440 *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
441 *	should be fixed rather than automatically determined. Can only be
442 *	executed on a network interface that is UP, and fixed BSSID/FREQ
443 *	may be rejected. Another optional parameter is the beacon interval,
444 *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
445 *	given defaults to 100 TU (102.4ms).
446 * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
447 *	determined by the network interface.
448 *
449 * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
450 *	to identify the device, and the TESTDATA blob attribute to pass through
451 *	to the driver.
452 *
453 * @NL80211_CMD_CONNECT: connection request and notification; this command
454 *	requests to connect to a specified network but without separating
455 *	auth and assoc steps. For this, you need to specify the SSID in a
456 *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
457 *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
458 *	%NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
459 *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
460 *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
461 *	%NL80211_ATTR_WIPHY_FREQ_HINT.
462 *	If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
463 *	restrictions on BSS selection, i.e., they effectively prevent roaming
464 *	within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
465 *	can be included to provide a recommendation of the initial BSS while
466 *	allowing the driver to roam to other BSSes within the ESS and also to
467 *	ignore this recommendation if the indicated BSS is not ideal. Only one
468 *	set of BSSID,frequency parameters is used (i.e., either the enforcing
469 *	%NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
470 *	%NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
471 *	Background scan period can optionally be
472 *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
473 *	if not specified default background scan configuration
474 *	in driver is used and if period value is 0, bg scan will be disabled.
475 *	This attribute is ignored if driver does not support roam scan.
476 *	It is also sent as an event, with the BSSID and response IEs when the
477 *	connection is established or failed to be established. This can be
478 *	determined by the STATUS_CODE attribute.
479 * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
480 *	sent as an event when the card/driver roamed by itself.
481 * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
482 *	userspace that a connection was dropped by the AP or due to other
483 *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
484 *	%NL80211_ATTR_REASON_CODE attributes are used.
485 *
486 * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
487 *	associated with this wiphy must be down and will follow.
488 *
489 * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
490 *	channel for the specified amount of time. This can be used to do
491 *	off-channel operations like transmit a Public Action frame and wait for
492 *	a response while being associated to an AP on another channel.
493 *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
494 *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
495 *	frequency for the operation.
496 *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
497 *	to remain on the channel. This command is also used as an event to
498 *	notify when the requested duration starts (it may take a while for the
499 *	driver to schedule this time due to other concurrent needs for the
500 *	radio).
501 *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
502 *	that will be included with any events pertaining to this request;
503 *	the cookie is also used to cancel the request.
504 * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
505 *	pending remain-on-channel duration if the desired operation has been
506 *	completed prior to expiration of the originally requested duration.
507 *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
508 *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
509 *	uniquely identify the request.
510 *	This command is also used as an event to notify when a requested
511 *	remain-on-channel duration has expired.
512 *
513 * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
514 *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
515 *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
516 *
517 * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
518 *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
519 *	requires an interface index, a frame type attribute (optional for
520 *	backward compatibility reasons, if not given assumes action frames)
521 *	and a match attribute containing the first few bytes of the frame
522 *	that should match, e.g. a single byte for only a category match or
523 *	four bytes for vendor frames including the OUI. The registration
524 *	cannot be dropped, but is removed automatically when the netlink
525 *	socket is closed. Multiple registrations can be made.
526 * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
527 *	backward compatibility
528 * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
529 *	command is used both as a request to transmit a management frame and
530 *	as an event indicating reception of a frame that was not processed in
531 *	kernel code, but is for us (i.e., which may need to be processed in a
532 *	user space application). %NL80211_ATTR_FRAME is used to specify the
533 *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
534 *	to indicate on which channel the frame is to be transmitted or was
535 *	received. If this channel is not the current channel (remain-on-channel
536 *	or the operational channel) the device will switch to the given channel
537 *	and transmit the frame, optionally waiting for a response for the time
538 *	specified using %NL80211_ATTR_DURATION. When called, this operation
539 *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
540 *	TX status event pertaining to the TX request.
541 *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
542 *	management frames at CCK rate or not in 2GHz band.
543 *	%NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
544 *	counters which will be updated to the current value. This attribute
545 *	is used during CSA period.
546 * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
547 *	command may be used with the corresponding cookie to cancel the wait
548 *	time if it is known that it is no longer necessary.
549 * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
550 * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
551 *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
552 *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
553 *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
554 *	the frame.
555 * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
556 *	backward compatibility.
557 *
558 * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
559 * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
560 *
561 * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
562 *	is used to configure connection quality monitoring notification trigger
563 *	levels.
564 * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
565 *	command is used as an event to indicate the that a trigger level was
566 *	reached.
567 * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
568 *	and the attributes determining channel width) the given interface
569 *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
570 *	In case multiple channels are supported by the device, the mechanism
571 *	with which it switches channels is implementation-defined.
572 *	When a monitor interface is given, it can only switch channel while
573 *	no other interfaces are operating to avoid disturbing the operation
574 *	of any other interfaces, and other interfaces will again take
575 *	precedence when they are used.
576 *
577 * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
578 *
579 * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
580 *	mesh config parameters may be given.
581 * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
582 *	network is determined by the network interface.
583 *
584 * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
585 *	notification. This event is used to indicate that an unprotected
586 *	deauthentication frame was dropped when MFP is in use.
587 * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
588 *	notification. This event is used to indicate that an unprotected
589 *	disassociation frame was dropped when MFP is in use.
590 *
591 * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
592 *      beacon or probe response from a compatible mesh peer.  This is only
593 *      sent while no station information (sta_info) exists for the new peer
594 *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
595 *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
596 *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
597 *      notification, userspace may decide to create a new station
598 *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
599 *      reoccurring, the userspace authentication daemon may want to create the
600 *      new station with the AUTHENTICATED flag unset and maybe change it later
601 *      depending on the authentication result.
602 *
603 * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
604 * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
605 *	Since wireless is more complex than wired ethernet, it supports
606 *	various triggers. These triggers can be configured through this
607 *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
608 *	more background information, see
609 *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
610 *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
611 *	from the driver reporting the wakeup reason. In this case, the
612 *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
613 *	for the wakeup, if it was caused by wireless. If it is not present
614 *	in the wakeup notification, the wireless device didn't cause the
615 *	wakeup but reports that it was woken up.
616 *
617 * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
618 *	the necessary information for supporting GTK rekey offload. This
619 *	feature is typically used during WoWLAN. The configuration data
620 *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
621 *	contains the data in sub-attributes). After rekeying happened,
622 *	this command may also be sent by the driver as an MLME event to
623 *	inform userspace of the new replay counter.
624 *
625 * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
626 *	of PMKSA caching dandidates.
627 *
628 * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
629 *	In addition, this can be used as an event to request userspace to take
630 *	actions on TDLS links (set up a new link or tear down an existing one).
631 *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
632 *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
633 *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
634 *	%NL80211_TDLS_TEARDOWN).
635 * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
636 *	%NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
637 *	sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
638 *	802.11 management frames, while TDLS action codes (802.11-2012
639 *	8.5.13.1) will be encapsulated and sent as data frames. The currently
640 *	supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
641 *	and the currently supported TDLS actions codes are given in
642 *	&enum ieee80211_tdls_actioncode.
643 *
644 * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
645 *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
646 *	implement sending deauth to stations that send unexpected class 3
647 *	frames. Also used as the event sent by the kernel when such a frame
648 *	is received.
649 *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
650 *	other attributes like the interface index are present.
651 *	If used as the command it must have an interface index and you can
652 *	only unsubscribe from the event by closing the socket. Subscription
653 *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
654 *
655 * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
656 *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
657 *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
658 *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
659 *
660 * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
661 *	by sending a null data frame to it and reporting when the frame is
662 *	acknowleged. This is used to allow timing out inactive clients. Uses
663 *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
664 *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
665 *	up the event with the request. The event includes the same data and
666 *	has %NL80211_ATTR_ACK set if the frame was ACKed.
667 *
668 * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
669 *	other BSSes when any interfaces are in AP mode. This helps implement
670 *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
671 *	messages. Note that per PHY only one application may register.
672 *
673 * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
674 *      No Acknowledgement Policy should be applied.
675 *
676 * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
677 *	independently of the userspace SME, send this event indicating
678 *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
679 *	attributes determining channel width.  This indication may also be
680 *	sent when a remotely-initiated switch (e.g., when a STA receives a CSA
681 *	from the remote AP) is completed;
682 *
683 * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
684 *	has been started on an interface, regardless of the initiator
685 *	(ie. whether it was requested from a remote device or
686 *	initiated on our own).  It indicates that
687 *	%NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
688 *	after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's.  The userspace may
689 *	decide to react to this indication by requesting other
690 *	interfaces to change channel as well.
691 *
692 * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
693 *	its %NL80211_ATTR_WDEV identifier. It must have been created with
694 *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
695 *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
696 *	public action frame TX.
697 * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
698 *	its %NL80211_ATTR_WDEV identifier.
699 *
700 * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
701 *	notify userspace that AP has rejected the connection request from a
702 *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
703 *	is used for this.
704 *
705 * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
706 *	for IBSS or MESH vif.
707 *
708 * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
709 *	This is to be used with the drivers advertising the support of MAC
710 *	address based access control. List of MAC addresses is passed in
711 *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
712 *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
713 *	is not already done. The new list will replace any existing list. Driver
714 *	will clear its ACL when the list of MAC addresses passed is empty. This
715 *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
716 *	ACL list during %NL80211_CMD_STOP_AP.
717 *
718 * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
719 *	a radar is detected or the channel availability scan (CAC) has finished
720 *	or was aborted, or a radar was detected, usermode will be notified with
721 *	this event. This command is also used to notify userspace about radars
722 *	while operating on this channel.
723 *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
724 *	event.
725 *
726 * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
727 *	i.e. features for the nl80211 protocol rather than device features.
728 *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
729 *
730 * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
731 *	Information Element to the WLAN driver
732 *
733 * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
734 *	to the supplicant. This will carry the target AP's MAC address along
735 *	with the relevant Information Elements. This event is used to report
736 *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
737 *
738 * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
739 *	a critical protocol that needs more reliability in the connection to
740 *	complete.
741 *
742 * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
743 *	return back to normal.
744 *
745 * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
746 * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
747 *
748 * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
749 *	the new channel information (Channel Switch Announcement - CSA)
750 *	in the beacon for some time (as defined in the
751 *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
752 *	new channel. Userspace provides the new channel information (using
753 *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
754 *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
755 *	other station that transmission must be blocked until the channel
756 *	switch is complete.
757 *
758 * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
759 *	by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
760 *	%NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
761 *	%NL80211_ATTR_VENDOR_DATA.
762 *	For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
763 *	used in the wiphy data as a nested attribute containing descriptions
764 *	(&struct nl80211_vendor_cmd_info) of the supported vendor commands.
765 *	This may also be sent as an event with the same attributes.
766 *
767 * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
768 *	The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
769 *	that attribute is not included, QoS mapping is disabled. Since this
770 *	QoS mapping is relevant for IP packets, it is only valid during an
771 *	association. This is cleared on disassociation and AP restart.
772 *
773 * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
774 *	%NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
775 *	and %NL80211_ATTR_ADMITTED_TIME parameters.
776 *	Note that the action frame handshake with the AP shall be handled by
777 *	userspace via the normal management RX/TX framework, this only sets
778 *	up the TX TS in the driver/device.
779 *	If the admitted time attribute is not added then the request just checks
780 *	if a subsequent setup could be successful, the intent is to use this to
781 *	avoid setting up a session with the AP when local restrictions would
782 *	make that impossible. However, the subsequent "real" setup may still
783 *	fail even if the check was successful.
784 * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
785 *	and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
786 *	before removing a station entry entirely, or before disassociating
787 *	or similar, cleanup will happen in the driver/device in this case.
788 *
789 * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
790 *	destination %NL80211_ATTR_MAC on the interface identified by
791 *	%NL80211_ATTR_IFINDEX.
792 *
793 * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
794 *	bandwidth of a channel must be given.
795 * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
796 *	network is determined by the network interface.
797 *
798 * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
799 *	identified by the %NL80211_ATTR_MAC parameter. A target channel is
800 *	provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
801 *	channel width/type. The target operating class is given via
802 *	%NL80211_ATTR_OPER_CLASS.
803 *	The driver is responsible for continually initiating channel-switching
804 *	operations and returning to the base channel for communication with the
805 *	AP.
806 * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
807 *	peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
808 *	when this command completes.
809 *
810 * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
811 *	as an event to indicate changes for devices with wiphy-specific regdom
812 *	management.
813 *
814 * @NL80211_CMD_MAX: highest used command number
815 * @__NL80211_CMD_AFTER_LAST: internal use

1400 * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
1401 *	allows auth frames in a mesh to be passed to userspace for processing via

1420 *	that match any of the sets will be reported.  These are
1421 *	pass-thru filter rules.
1422 *	For a match to succeed, the BSS must match all attributes of a
1423 *	set.  Since not every hardware supports matching all types of
1424 *	attributes, there is no guarantee that the reported BSSs are
1425 *	fully complying with the match sets and userspace needs to be
1426 *	able to ignore them by itself.
1427 *	Thus, the implementation is somewhat hardware-dependent, but
1428 *	this is only an optimization and the userspace application
1429 *	needs to handle all the non-filtered results anyway.
1430 *	If the match attributes don't make sense when combined with
1431 *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1432 *	is included in the probe request, but the match attributes

2293 * These attribute types are used with %NL80211_STA_INFO_TXRATE
2294 * when getting information about the bitrate of a station.
2295 * There are 2 attributes for bitrate, a legacy one that represents
2296 * a 16-bit value, and new one that represents a 32-bit value.
2297 * If the rate value fits into 16 bit, both attributes are reported
2298 * with the same value. If the rate is too high to fit into 16 bits
2299 * (>6.5535Gbps) only 32-bit attribute is included.
2300 * User space tools encouraged to use the 32-bit attribute and fall
2301 * back to the 16-bit one for compatibility with older kernels.

3832 * DOC: TCP connection wakeup
3833 *
3834 * Some devices can establish a TCP connection in order to be woken up by a
3835 * packet coming in from outside their network segment, or behind NAT. If
3836 * configured, the device will establish a TCP connection to the given
3837 * service, and periodically send data to that service. The first data
3838 * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
3839 * The data packets can optionally include a (little endian) sequence
3840 * number (in the TCP payload!) that is generated by the device, and, also
3841 * optionally, a token from a list of tokens. This serves as a keep-alive
3842 * with the service, and for NATed connections, etc.
3843 *
3844 * During this keep-alive period, the server doesn't send any data to the
3845 * client. When receiving data, it is compared against the wakeup pattern
3846 * (and mask) and if it matches, the host is woken up. Similarly, if the
3847 * connection breaks or cannot be established to start with, the host is
3848 * also woken up.
3849 *
3850 * Developer's note: ARP offload is required for this, otherwise TCP
3851 * response packets might not go through correctly.

4230 *	socket option.
4231 * @NL80211_FEATURE_HT_IBSS: This driver supports IBSS with HT datarates.
4232 * @NL80211_FEATURE_INACTIVITY_TIMER: This driver takes care of freeing up
4233 *	the connected inactive stations in AP mode.
4234 * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
4235 *	to work properly to suppport receiving regulatory hints from
4236 *	cellular base stations.
4237 * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: (no longer available, only
4238 *	here to reserve the value for API/ABI compatibility)
4239 * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of
4240 *	equals (SAE) with user space SME (NL80211_CMD_AUTHENTICATE) in station
4241 *	mode
4242 * @NL80211_FEATURE_LOW_PRIORITY_SCAN: This driver supports low priority scan
4243 * @NL80211_FEATURE_SCAN_FLUSH: Scan flush is supported
4244 * @NL80211_FEATURE_AP_SCAN: Support scanning using an AP vif
4245 * @NL80211_FEATURE_VIF_TXPOWER: The driver supports per-vif TX power setting
4246 * @NL80211_FEATURE_NEED_OBSS_SCAN: The driver expects userspace to perform
4247 *	OBSS scans and generate 20/40 BSS coex reports. This flag is used only
4248 *	for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.
4249 * @NL80211_FEATURE_P2P_GO_CTWIN: P2P GO implementation supports CT Window
4250 *	setting
4251 * @NL80211_FEATURE_P2P_GO_OPPPS: P2P GO implementation supports opportunistic

4254 *	transitions for AP clients. Without this flag (and if the driver
4255 *	doesn't have the AP SME in the device) the driver supports adding
4256 *	stations only when they're associated and adds them in associated
4257 *	state (to later be transitioned into authorized), with this flag
4258 *	they should be added before even sending the authentication reply
4259 *	and then transitioned into authenticated, associated and authorized
4260 *	states using station flags.
4261 *	Note that even for drivers that support this, the default is to add
4262 *	stations in authenticated/associated state, so to add unauthenticated
4263 *	stations the authenticated/associated bits have to be set in the mask.
4264 * @NL80211_FEATURE_ADVERTISE_CHAN_LIMITS: cfg80211 advertises channel limits
4265 *	(HT40, VHT 80/160 MHz) if this flag is set

4267 *	Peering Management entity which may be implemented by registering for
4268 *	beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
4269 *	still generated by the driver.
4270 * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
4271 *	interface. An active monitor interface behaves like a normal monitor
4272 *	interface, but gets added to the driver. It ensures that incoming
4273 *	unicast packets directed at the configured interface address get ACKed.
4274 * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
4275 *	channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
4276 *	lifetime of a BSS.
4277 * @NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES: This device adds a DS Parameter
4278 *	Set IE to probe requests.
4279 * @NL80211_FEATURE_WFA_TPC_IE_IN_PROBES: This device adds a WFA TPC Report IE
4280 *	to probe requests.
4281 * @NL80211_FEATURE_QUIET: This device, in client mode, supports Quiet Period
4282 *	requests sent to it by an AP.
4283 * @NL80211_FEATURE_TX_POWER_INSERTION: This device is capable of inserting the
4284 *	current tx power value into the TPC Report IE in the spectrum
4285 *	management TPC Report action frame, and in the Radio Measurement Link
4286 *	Measurement Report action frame.
4287 * @NL80211_FEATURE_ACKTO_ESTIMATION: This driver supports dynamic ACK timeout
4288 *	estimation (dynack). %NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used
4289 *	to enable dynack.
4290 * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
4291 *	multiplexing powersave, ie. can turn off all but one chain
4292 *	even on HT connections that should be using more chains.
4293 * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
4294 *	multiplexing powersave, ie. can turn off all but one chain
4295 *	and then wake the rest up as required after, for example,
4296 *	rts/cts handshake.
4297 * @NL80211_FEATURE_SUPPORTS_WMM_ADMISSION: the device supports setting up WMM
4298 *	TSPEC sessions (TID aka TSID 0-7) with the %NL80211_CMD_ADD_TX_TS
4299 *	command. Standard IEEE 802.11 TSPEC setup is not yet supported, it
4300 *	needs to be able to handle Block-Ack agreements and other things.
4301 * @NL80211_FEATURE_MAC_ON_CREATE: Device supports configuring
4302 *	the vif's MAC address upon creation.
4303 *	See 'macaddr' field in the vif_params (cfg80211.h).

4305 *	operating as a TDLS peer.
4306 * @NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR: This device/driver supports using a
4307 *	random MAC address during scan (if the device is unassociated); the
4308 *	%NL80211_SCAN_FLAG_RANDOM_ADDR flag may be set for scans and the MAC
4309 *	address mask/value will be used.

4311 *	using a random MAC address for every scan iteration during scheduled
4312 *	scan (while not associated), the %NL80211_SCAN_FLAG_RANDOM_ADDR may
4313 *	be set for scheduled scan and the MAC address mask/value will be used.
4314 * @NL80211_FEATURE_ND_RANDOM_MAC_ADDR: This device/driver supports using a
4315 *	random MAC address for every scan iteration during "net detect", i.e.
4316 *	scan in unassociated WoWLAN, the %NL80211_SCAN_FLAG_RANDOM_ADDR may
4317 *	be set for scheduled scan and the MAC address mask/value will be used.
