The queue is already available, we make sure of that before calling
ath_tx_start().
And the queue is sent through txctl.txq, you don't have to calculate the queue
number again.
So, just stopping the queue and moving the buffer back to the free list would
be enough.

The target beacon transmission time has to be synced with the HW
TSF when configuring beacon timers in Adhoc mode. Failing to do this
would cause erroneous beacon transmission, for example, on completion
of a scan run to check for IBSS merges

In multi-interface mode, beacons/probe responses that are
sent out must have their timestamp field updated. Calculate
the TSF adjustment value for each beaconing interface and set it
in the frame properly.

Use the CAB endpoint to send buffered multicast or
broadcast frames after each SWBA event.

Use a queue to handle WMI events and schedule a tasklet
to process the events. This fixes the race between the
WMI event ISR and the SWBA tasklet when the arrival of
WMI events in quick succession could overwrite the SWBA
data before the tasklet

The AID and BSSID should be set in the HW only for the
first station interface or adhoc interface. Also, cancel
the ANI timer in stop() for multi-STA scenario. And finally
configure the HW beacon timers only for the first station
interface

The length of the received SKB could be equal to
HTC_RX_FRAME_HEADER_SIZE in case of packets with phy/crc errors,
in which case they are dropped without being processed.
Fix this check so that the error counters are updated correctly.

There is no need to set the BSSID mask or opmode when
initializing RX, they would be set correctly in the HW reset
routine.

For all packets sent through the USB_WLAN_TX_PIPE endpoint,
the private area of the SKB's tx_info can be used to store
driver-specific information. For packets sent through USB_REG_OUT_PIPE,
this will not make a difference since they are routed

Transmission of beacons becomes erratic when TX load
is high, since the latency involved in the generation
of a SWBA interrupt on the target to the actual sending
of a beacon is quite high for USB devices.
Fix this by adjusting the beacon
