Given that there's no data coming from network stack for binding flows,
hence driver counts and reports station's statistics directly through
NL80211_STA_INFO_* based on active PPDU based TxS for offloading data.
Apart from that, WA firmware and its offloading engine (SDO) have hardcoded
"2" as PID, so we introduce MT_PACKET_ID_WED to differentiate WED reporting.
Note that PPDU format TxS is mutually exclusive with MT_TXD5_TX_STATUS_HOST.

Previously the code used skb_set_queue_mapping for management or non-bufferable
powersave frames that need to be sent to a different hardware queue.
This can confuse AQL, which expects the value to remain the same until the tx
status report.
The only place that currently uses the altered skb queue mapping is the txwi
write function. Change the code to pass the hardware queue id as a function
parameter instead.

Before, the hardware would be allowed to transmit injected 802.11 MPDUs
as A-MSDU. This resulted in corrupted frames being transmitted. Now,
injected MPDUs are transmitted as-is, without A-MSDU.
The fix was verified with frame injection on MT7915 hardware, both with
and without the injected frame being encrypted.
If the hardware cannot do A-MSDU aggregation on MPDUs, this problem
would also be present in the TX path where mac80211 does the 802.11
encapsulation. However, I have not observed any such problem when
disabling IEEE80211_HW_SUPPORTS_TX_ENCAP_OFFLOAD to force that mode.
Therefore this fix is isolated to injected frames only.
The same A-MSDU logic is also present in the mt7921 driver, so it is
likely that this fix should be applied there too. I do not have access
to mt7921 hardware so I have not been able to test that.
