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.

2022-09-12wifi: rtw89: 8852c: support hw_scanPo-Hao Huang
This enables hw_scan function for 52c. The mechanism is similar to 52a except that it adds modifications required for 6G channels and extends the command length to make driver compatible to both newer and existing firmware.

2022-09-12wifi: rtw89: call tx_wake notify for 8852c in deep ps modeChin-Yen Lee
8852c transmits packets with slow response in deep ps mode, and lead to low throughput. We need to call tx_wake for each pakcet to trigger firmware wake earlier to avoid it.

2022-09-12wifi: rtw89: set response rate selectionChia-Yuan Li
With suitable response rate, it can acknowledge peer packets are received. Otherwise, peer could re-transmit again due to missing of ACK frames. To achieve this, refer to RX rate and CMAC table to choose the smaller as initial response rate.

2022-09-12wifi: rtw89: 8852c: enlarge polling timeout of RX DCKPing-Ke Shih
The range of calibration time of RX DCK is quite wide from ~40us to ~1300us by experiments, and probability is about 0.1% for the cases larger than 1000us. Though it can retry calibration and get positive result, it will spend more time. Therefore, enlarge it to avoid warning and duplicate calibration.
