We always wait for CMD_CALIBRATION_OP mcu message, but wait argument is used
for do additional MT_MCU_COM_REG0 register operations, which are needed
for mt76x2e devices and we can use appropriate check instead of wait argument.

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.

So far the code only validates the buffer size of the first skb.
Extend this check to cover additional fragments as well, in case the size
is corrupted during a DMA reset.
Signed-off-by: Felix Fietkau <[email protected]>
Use 4096 as maximum size instead of the rx buffer size, since rx packets
can be split across multiple buffers. This fixes issues with receiving
A-MSDU aggregated packets.

There is some code in the mac80211 tx status processing code that could
potentially call back into the tx codepath.
To avoid deadlocks, make sure that no tx related spinlocks are taken
during the ieee80211_tx_status call.

Assure that after we initialize dev->cal.low_gain to -1 this

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.
