Stanislaw GruszkaandFelix Fietkau a2380992d8 mt76: create new mt76x02-lib module for common mt76x{0,2} code 
Move rxfilter and mutex to common structure. Create mt76x02-lib.ko
for mt76x0 and mt76x2 common functions and create new unified
mt76x02_configure_filter() function there.

Lorenzo BianconiandFelix Fietkau 730b86c73a mt76x2: add napi struct to mt76_rx_poll_complete/mt76_rx_complete signatures 
in order to reuse mt76_rx_complete routine supporting mt76x2u based
devices add napi struct to mt76_rx_poll_complete and mt76_rx_complete
routine signatures and do not fetch it according to the rx queue index

Move  wiphy interface_modes definition in mt76x2_init in order to

Felix Fietkau 0ef26ef052 mt76: only stop tx queues on offchannel, not during the entire scan 
During scans, mac80211 frequently switches back to the home channel to
minimize interruption of ongoing traffic. Keep regular tx queues active
during that time.

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.

Felix Fietkau f515dfcca1 mt76: implement AP_LINK_PS 
With software A-MPDU reordering in place, frames that notify mac80211 of

stalls. Fix this by implementing powersave state processing in the
driver.
