iwlwifi: mvm: prepare for scheduler config command
The scheduler is a HW sub-block that directs the work of the Flow
Handler by issuing requests for frame transfers, specifying source
and destination. Its primary function is to allocate flows into the
TX FIFOs based upon a pre-determined mapping.
The driver has some responsibilities to the scheduler, namely
initialising and maintaining the hardware registers. This is
currently done by directly accessing them, which can cause races
with the firmware also accessing the registers.
To address this problem, change the driver to no longer directly
access the registers but go through the firmware for this if the
firmware has support for DQA and thus the new command.

There are a few places that can call the function
iwl_mvm_mac_get_queues_mask() instead of open-coding the
equivalent, so do that. This requires changing it to return
the multicast queue as part of the bitmap, which broke GO
mode because including it in the broadcast station queues
seems to confuse the firmware, so work around that.
Also, the API defines that the CAB queue shouldn't be
included in the TFD queue mask, adjust the comment

iwlwifi: mvm: correct firmware disassoc command sequence
The firmware would like to have a MAC context (unassoc)
before the AP station is removed (we do this) but would
like to keep the BSSID until after it is removed, so we
need to send two commands - one with the BSSID before
and one without the BSSID after.
In order to do this, we need to store the BSSID as it
will have been cleared by mac80211 by the time we get
notified of the disassociation. Also pass it around as
an override to the various functions needing it, and
keep taking it from the mac80211 data otherwise. This
avoids having to keep track of the BSSID in all modes.

iwlwifi: mvm: don't set the MCAST queue in STA's queue list
The MCAST queue should be enabled after DTIM only.
According to fw API, the MCAST must not be attached to any
station, but should appear in the mcast_qid of the AP's
mac context only.

iwlwifi: mvm: correctly configure MCAST in AP mode
The AP mode needs to use the MCAST fifo for the MCAST
frames sent after the DTIM. This fifo needs to be
configured with the same parameters as the VOICE FIFO.
A separate SCD queue is mapped to this fifo - the cab_queue
(cab stands for Content After Beacon). This queue isn't
connected to any station, but rather to the MAC context.
This queue should (and is already) be set as the MCAST
queue - this is part of the of MAC context command.

iwlwifi: mvm: Add support for connection monitor offload
The firmware supports periodic keep alive and beacon monitoring,
so advertise connection monitor offload capability by setting
IEEE80211_HW_CONNECTION_MONITOR flag. Implement missed beacons
notification handler. Call ieee80211_beacon_loss in case of
missed beacons, so AP probing by mac80211 can be triggered.

iwlwifi: mvm: add thermal throttling and CT kill
In order to avoid NIC destruction due to high temperature,
CT kill will power down the NIC.
To avoid this, thermal throttling will decrease throughput
to prevent the NIC from reaching the temperature at which
CT kill is performed.

iwlwifi: mvm: Prevent setting assoc flag in MAC_CONTEXT_CMD
In the normal flow first MAC_CONTEXT_CMD for particular interface is
never sent while associated. The exception is fw restart flow when
resuming from suspend when WoWLAN is enabled. In this case successive
"add" and "modify" MAC_CONTEXT_CMD commands may be sent with assoc flag
set what cause FW mal functioning. To prevent this never set assoc flag
in MAC_CONTEXT_CMD with action "add".

iwlwifi: mvm: don't read system time when modifying AP/GO MAC
When modifying a MAC, we update its beacon system time which
is taken as a base to calculate TBTT. The firmware doesn't use
the new timestamp because the time is never used after the MAC
and broadcast station were added, but it is safer to not rely
on this and avoids the overhead of reading the register every
time the MAC is updated.

iwlwifi: mvm: program DTIM timings properly
For the firmware to know when DTIM beacons arrive
we have to program the DTIM time in TSF and system
time in the MAC context. Since mac80211 now tracks
the different times (on demand), this becomes easy.

iwlwifi: mvm: don't delay the association until after beacon
If we haven't heard a beacon before we associate we can
still start the association process and set the MAC in
the firmware to associated only after having received a
beacon with DTIM period by reacting to the new change
flag (BSS_CHANGED_DTIM_PERIOD) from mac80211.
This reduces the association time in these cases.
