Michal Kazior dbdcc2620b ath10k: remove extra_tx_headroom
Comment was out-of-date. The headroom is no longer
necessary because HTT Tx fragment list is stored

Ben Greear 5572a95b4b ath10k: apply chainmask settings to vdev on creation
It appears it takes more than just setting the
hardware's chainmask to make things work well.  Without
this patch, a vdev would only use 1x1 rates when chainmask
was set to 0x3.

Setting the 'nss' (number of spatial streams) on the vdev
helps the firmware's rate-control algorithm work properly.

Sujith Manoharan 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.

Sujith Manoharan 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.

When a pending roc or scan operation is cancelled,
the offchannel operation is cleared, but the offchannel

problems since an active GO will try to process a stale

Chun-Yeow Yeoh 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

This patch adds auto TDLS support to mwifiex.

Auto TDLS functionality works as follows:
1. Whenever userspace application has triggered TDLS connection with
any peer, driver would store this peer mac address details in its database.
2. After this driver whenever driver receives packet on direct link,
it would store rssi and timestamp in peer information.
3. Whenever a packet is to be transmitted to non-AP peer in station mode,
driver would check if TDLS link can be established by looking at peer RSSI
information. Driver would initiate TDLS setup in such cases.
4. Periodic timer is used for updating peer information.
5. Auto TDLS peer list & timer are cleared during disconnection or driver unload.
