wlcore: user smaller sqn padding for GEM
On recovery, we increase the current seq num by
WL1271_TX_SQN_POST_RECOVERY_PADDING in order to
compensate for packets we might have missed during
recovery.
It seems that some GEM APs have issues when the
gap is too big, so use a smaller padding in this case.

wlcore: save seq num only between recoveries
We want seq num (freed_pkts) to be initialized
on each new connection, but keep persistent
between recoveries/suspends.
Save the freed_pkts in the private block of the
sta struct (we already do a similar thing for
AP's stations).
However, keep the old wlvif->total_freed_pkts
in order to avoid too intrusive change.

mac80211: split sched scan IEs
Split sched scan IEs to band specific and not band specific
blocks. Common IEs blocks may be sent to the FW once per command,
instead of per band.
This allows optimization of size of the command, which may be
required by some drivers (eg. iwlmvm with newer firmware version).
As this changes the mac80211 API, update all drivers to use the
new version correctly, even if they don't (yet) make use of the
split data.

wlcore: consolidate tx_seq handling on recovery
Accumulate the total number of sent packets per-link to find out how far
the encryption sequence number has progressed. Use this number as the
initial security sequence number after recovery.
This consolidates security sequence handling for both chip families, as
we no longer have to rely on 12xx specific Tx completion.
A fortunate side effect of this is correct management of seq numbers for
AP roles and multi-role scenarios.
When a link is removed we save the last seq number on a persistent part
of the wlvif. This helps the data survive through recoveries/suspends,
which also entail changes in the hlid of the link.
This functionality is STA only currently.

In 18xx the calibration process of the PHY Cortex domain
requires to perform an active calibration of the channel
before it can be used for transmission. To fulfill world
wide regulatory restrictions, fw should be always
synchronized/updated with current CRDA configuration.
Add a new "CMD_DFS_CHANNEL_CONFIG" command to update the
fw with current reg-domain, this command passes a bit map
of channels that are allowed to be used for transmission.
The driver shall update the fw during initialization and
after each change in the current reg-domain
configuration. The driver will save the channel number of
incoming beacons during the scan process, as they might
be a result of the passive scan on
"IEEE80211_CHAN_PASSIVE_SCAN" channel and will update the
fw accordingly once the scan is finished, the purpose of
this is to be ready in case of the authentication request
on one of these disabled (uncalibrated) channels.
The new command requires to wait for the fw completion
event "DFS_CHANNELS_CONFIG_COMPLETE_EVENT".
No scan commands (including the sched scan) can be
executed concurrently with the "CMD_DFS_CHANNEL_CONFIG",
wl->mutex ensures that.

wlcore: lazy-enable device roles
Enable device roles just before starting it.
This way, a single device role should be enough
for all vifs, as we can't use concurrent device
roles (which require ROC) anyway.

wlcore: Prevent interaction with HW after recovery is queued
When a function requests to recover, it would normally abort and will
not send any additional commands to the HW. However, other threads may
not be aware of the failure and could try to communicate with the HW
after a recovery was queued, but before the recovery work began.
Fix this by introducing an intermediate state which is set when recovery
is queued, and modify all state checks accordingly.

wlcore: wait for command completion event when sending CMD_ROLE_STOP
We need to wait for the command completion event when we send the
CMD_ROLE_STOP event otherwise we may try to send CMD_ROLE_START too
soon and get out-of-sync with the firmware.
In some cases, the firmware may not send the event, so we wait for the
event or for the timeout, whichever comes first.
This patch is based on an earlier version by Eliad.

wlcore: change the wait for event mechanism
wlcore needs to wait for certain events for example
for roc complete event. Usually the events are received
from the FW very fast, therefore wlcore can poll with
a short delay and if after a second the event was
not received yet poll with a long (1-5 msec) delay.
This implementation is similar to the sending of
commands to the FW.
Empirically the change reduced the wait for roc event
from ~10-40msec to 100s of usecs.

wlcore: add probe request templates for sched and one-shot scans
The driver configures the firmware template for probe requests during
the scan process. If the same template is used for one-shot and sched
scans they will override each other when running scans simultaneously.
This fix works only on firmwares later than X.3.9.2.112 for single
role and X.3.9.2.23 for multi-role.

wlcore: queue recovery in case of bus errors during cmd_remove_peer
Following the addition of propagating errors from the bus ops
there's a need to distinguish between bus errors (including timeout)
and a legitimate timeout occuring in cmd_wait_for_event_or_timeout.
In case of real bus errors we need to queue recovery even in cases
where a timeout on a response from the FW to a command is acceptable.

wlcore: wait for roc complete only for the first roc command
In some multi role scenarios the driver might send multi
roc requests without sending a croc first, the fw queues
those requests and starts service the next roc request as
soon as the driver sends a croc for the previous one. So,
if the fw rocs on channel X and driver asks to roc also
on channel Y, the fw will not start service Y (and will
not send roc complete event for this request) until the
driver releases the fw with croc X.

wlcore: use psd_type indexing according to spec
In ieee80211.h the uapsd bit mask is defined such that
VO=BIT(0), VI=BIT(1), BK=BIT(2), BE=BIT(3).
The firmware uses the indexing as defined in the ieee80211
spec, meaning that VO=3, VI=2, BK=1, BE=0.
In AP mode when adding peer wlcore needs to convert
the indexing accordingly.

wlcore: fix size of two memset's in wl1271_cmd_build_arp_rsp()
We currently do this:
int wl1271_cmd_build_arp_rsp(struct wl1271 *wl, struct wl12xx_vif *wlvif)
...
struct wl12xx_arp_rsp_template *tmpl;
struct ieee80211_hdr_3addr *hdr;
...
tmpl = (struct wl12xx_arp_rsp_template *)skb_put(skb, sizeof(*tmpl));
memset(tmpl, 0, sizeof(tmpl));
...
hdr = (struct ieee80211_hdr_3addr *)skb_push(skb, sizeof(*hdr));
memset(hdr, 0, sizeof(hdr));
...
I believe we want to set the entire structures to 0 with those
memset() calls, not just zero the initial part of them (size of the
pointer bytes).
