The masks were wrong. They should be 0xffffffff when SCO,
HID or SNIFF profiles are used. They should be 0xffff0000
in any other case (default) to get a bit more throughput
when the BT profile allows for it.

If wpa_supplicant and iw/iwconfig are used together, very
rarely the system crashes. It seems to be related to the
connection parameters not being set up, but it's not all
clear to me how this happens. In any case, checking that
the conn pointer exists here is probably a good idea.

There is a race between the restart flow and the workers.
The workers are cancelled after the fw is already killed
and might send HCMD when there is fw to handle them.
Simply check that there is a fw to which the HCMD can be
sent before actually sending it.

rt2800 hardware sometimes reorders tx frames when transmitting to
multiple BA enabled STAs concurrently.
For example a tx queue
[ STA1 | STA2 | STA1 | STA2 ]
can result in the tx status reports
[ STA1 | STA1 | STA2 | STA2 ]
when the hw decides to put the frames for STA1 in one AMPDU.
To mitigate this effect associate the currently processed tx status
to the first frame in the tx queue with a matching wcid.
This patch fixes several problems related to incorrect tx status
reporting. Furthermore the tx rate selection is much more stable when
communicating with multiple STAs.

mwifiex_send_cmd_async() is called for sync as well as async
commands. (mwifiex_send_cmd_sync() internally calls it for
sync command.)
"adapter->cmd_queued" gets filled inside mwifiex_send_cmd_async()
routine for both types of commands. But it is used only for sync
commands in mwifiex_wait_queue_complete(). This could lead to a
race when two threads try to queue a sync command with another
sync/async command simultaneously.
Get rid of global variable and pass command node as a parameter
to mwifiex_wait_queue_complete() to fix the problem.

The commit 'ath9k_hw: fix calibration issues on chainmask that don't
include chain 0' changed the hardware chainmask to the chip chainmask
for the duration of the calibration, but the revert to user
configuration in the reset path runs too early.
That causes some issues with limiting the number of antennas (including
spurious failure in hardware-generated packets).
Fix this by reverting the chainmask after the essential parts of the
calibration that need the workaround, and before NF calibration is run.
