This makes it easier to loop powersave-filtered packets through the MCU queue
without involving the firmware

Starting from mac80211 commit adf8ed01e4fd ("mac80211: add an optional
TXQ for other PS-buffered frames") and commit 0eeb2b674f05 ("mac80211:
add an option for station management TXQ") a new per-sta queue has been
introduced for bufferable management frames.
sta->txq[IEEE80211_NUM_TIDS] is initialized just if the driver reports
the following hw flags:
- IEEE80211_HW_STA_MMPDU_TXQ
- IEEE80211_HW_BUFF_MMPDU_TXQ
This can produce a NULL pointer dereference in mt76_stop_tx_queues
since mt76 iterates on all available sta tx queues assuming they are
initialized by mac80211. This issue has been spotted analyzing the code
(it has not triggered any crash yet)

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.

Initialize bss_info_changed mac80211 callback to
mt76x02_bss_info_changed utility routine and remove duplicated code.

connection establishment since NetworkManager perform multiple frequency

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.

Add support for parsing legacy rates, use a flag in the tx status info
as indicator for fixed rate packets
Signed-off-by: Felix Fietkau <[email protected]>
The FIXED_RATE flag of txd6 does not enable fixed rate, it only configures
the use of the fixed rate register as rate source.
Set the right flag in txd2 instead.

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.

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.
