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.

mt7921s driver may receive frames with fragment buffers. If there is a
CTS packet received in monitor mode, the payload is 10 bytes only and
need 6 bytes header padding after RXD buffer. However, only RXD in the
first linear buffer, if we pull buffer size RXD-size+6 bytes with
skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in
__skb_pull().
To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to
256 to make sure all MCU operation in linear buffer.

Client mode on DFS channels was broken, because the old code was activating
the DFS detector on radar channels while leaving it in CAC state.
This was caused by making the decision based on the channel radar flag,
instead of hw->conf.radar_enabled.
In order to properly deal with the various corner cases, rip out the state
handling code and replace it with something that's much easier to reason
about.

We don't have to create a separate sdio.xmit_buf buffer for each queue.
Instead, we just need to create one, reuse it across all queues to reduce
memory consumption further.
And then we should take it into account the actual the host and the device
MMC capability to determine what the appropriate xmit_buf_size can be.
Both MT7921S and MT7663 can support up to Tx FIFO size of 0x3fe00 which
means the device can receive 511 blocks of block size 512 in a row from
the host. So if the driver aggregates the frames as many as possible the
the device can support, we can merge multiple MMC requests into a single
one to get rid of the overhead of the handling and synchronizing in those
unnecessary MMC requests and reduce the SDIO lock contention with the
Bluetooth concurrent traffic and finally to have the higher bus
utilization with less idle cycle.
With the patch, it is helpful for WiFi to have steady throughput
performance especially while running Bluetooth concurrently.
