Felix Fietkau ca5cc9a478 mt76: fix concurrent rx calls on A-MPDU release 
Add a spinlock in mt76_rx_complete. Without this, multiple stats updates
could happen in parallel, which can lead to deadlocks. There are
probably more corner cases fixed by this change.

Lorenzo BianconiandFelix Fietkau ced433d006 mt76x2: add mac80211 {set,get}_antenna callbacks 
Add capability to select tx/rx antennas. Possible values are:
 - 1: to use only the first antenna
 - 2: to use only the second antenna
 - 3: to use both of them

Lorenzo BianconiandFelix Fietkau 7e6e00bf0a mt76: initialize available_antennas_{tx,rx} info 
Initialize available_antennas related info in wiphy data structure
according to antenna_mask field; antenna_mask info is initialized
in device specific code and will be used in mac80211 {set,get}_antenna
callbacks

Felix Fietkau f515dfcca1 mt76: implement AP_LINK_PS 
With software A-MPDU reordering in place, frames that notify mac80211 of
powersave changes are reordered as well, which can cause connection
stalls. Fix this by implementing powersave state processing in the
driver.

Felix Fietkau 792859b237 mt76x2: fix transmission of encrypted management frames 
Hardware encryption seems to break encrypted unicast mgmt tx.
Unfortunately the hardware TXWI header does not have a bit to indicate
that a frame is software encrypted, so sw-encrypted frames need to use a
different WCID. For that to work, the CCMP PN needs to be generated in
software, which makes things a bit slower, so only do it for keys that
also need to tx management frames.
