When mt76x0 and mt76x2 beacon code was unified, it changed the order in which
beacon enable and beacon interval are configured.
Configuring beacon enable before beacon interval can in some cases cause
problems with the beacon timer, leading to clients not waking up properly
from powersave mode.
Fix this by changing the order back to interval first, then enable.

If there are still pending packets in the tx queue when removing a station,
it could possibly lead to a call to further attempts to pull packets from
the mac80211 tx queue after it has already been removed from the scheduling
list.
Prevent this from happening by calling synchronize_rcu after deleting the
wcid pointer before further cleaning up the tx queues.
To be extra careful, ensure that mtxq->list is always initialized properly.
Also drop the useless call to mt76x02_mac_wcid_setup, which only re-assigns
the bss index of the wcid entry, but does not help with the cleanup in any
way.

There is some code in the mac80211 tx status processing code that could

If we are associated and scanning is performed, sw_scan_complete callback
is done after we get back to operating channel, so we do not perform
queue cal work. Fix this queue cal work from sw_scan_complete().
On mt76x0 we have to restore gain in MT_BBP(AGC, 8) register after
scanning, as it was multiple times modified by channel switch code.
So queue cal work without any delay to set AGC gain value.
Similar like in mt76x2 init AGC gain only when set operating channel
and just check before queuing cal work in sw_scan_complete() if
initialization was already done.

MT76x2/MT76x0 has somewhat unreliable tx status reporting, and for that
reason the driver currently does not report per-skb tx ack status at all.
This breaks things like client idle polling, which relies on the tx ack
status of a transmitted nullfunc frame.
This patch adds code to report skb-attached tx status if requested by
mac80211 or the rate control module. Since tx status is polled from a
simple FIFO register, the code needs to account for the possibility of
tx status events getting lost.
The code keeps a list of skbs for which tx status is required and passes
them to mac80211 once tx status has been filled in and the DMA queue is
done with it.
If a tx status event is not received after one second, the status rates
are cleared, and a succesful ACK is indicated to avoid spurious disassoc
during assoc or client polling.
