b9fd8a8420 ath10k: use rx descriptor for ppdu status extraction
This makes it more in line with the new Rx path.
It also makes the code more reusable because Rx
descriptor is more accessible.

47b6308b64 ath9k: Move roc completion to the offchannel timer
Currently, when a roc period expires, the offchannel
timer calls ieee80211_remain_on_channel_expired(), but
the roc state is cleared only when the queued work
to switch to the operating channel gets a chance to run.

This race is a problem because mac80211 can issue a
new roc request in this window. To avoid this, handle
roc completion in the offchannel timer itself.

d9092c9873 ath9k: Adjust tbtt delta properly
In a GO/STA setup, when we switch to the STA context,
the channel context timer is scheduled with a period of
half the beacon interval. If a beacon is received in
this duration, the timer is adjusted to accommodate
TSF sync done by the HW.

But, if the actual channel switch is delayed for some
reason, we end up rearming the timer every time a new
beacon is received. Avoid this by doing the adjustment
only once.

6185672aba ath9k: Cancel pending offchannel operations
This patch makes sure that pending roc/scan
operations are cancelled properly when a new
context is assigned/unassigned.

The flush_work() call to flush out any scheduled
channel context work is removed, instead, sc->mutex
is dropped to allow any pending work to get a chance
to complete by the channel scheduler. Also, increase
the timeout to allow a switch to an active GO.

e21a1d8b2b ath9k: Clear offchannel state properly
When a pending roc or scan operation is cancelled,
the offchannel operation is cleared, but the offchannel
state in the main scheduler is not cleared. This causes
problems since an active GO will try to process a stale
offchannel request that was deferred earlier. Fix this
by clearing the state when there is no pending offchannel
(roc/scan) operation.

f4c34af4fc ath9k: Enable TSF2 for generic HW timers
The base TSF is used for HW timers 0..7, but chips
in the AR9003 family and above can support more generic
timers. To use them, however, a second HW TSF needs to
be enabled. This patch allows usage of the extra
timers by starting the second TSF properly.

The extra set of HW timers is apparently also present
in AR9287, but we enable it only for the AR9003 family.

60fc496254 ath9k_htc: Enable software crypto for mgmt frame in Tx for USB devices
In secured mesh, the unicast mgmt frame is encrypted using
the same key that used for encrypting the unicast data frame.
This patch "ath9k_htc_firmware: fix the offset of CCMP header
for mesh data frame" applied to open-ath9k-htc-firmware allows
the ath9k_htc to be loaded without "nohwcrypt=1". Unfortunately,
this is not working and we still need CCMP encryption of
transmitted management frames to be done in software.

So this patch allows the software encryption for transmitted
management frame to be done in software but remain the hardware
decryption for received management frame.

This patch is tested with the following hardwares:
- TP-Link TL-WN821N v3 802.11n [Atheros AR7010+AR9287]
- AR9271 802.11n

and managed to work with peer mesh STA equipped with ath9k.
