[ Upstream commit 8a9c06b40882ebea45563059ddc5d57acdec9dda ]
Currently, the transmit rate of "iw dev xxx station dump" command always show an invalid value.
To address this issue, ath12k parse the info of transmit complete report from firmware and indicate the transmit rate to mac80211.
This patch affects the station mode of WCN7850 and QCN9274.
After that, "iw dev xxx station dump" show the correct transmit rate. Such as:
Station 00:03:7f:12:03:03 (on wlo1) inactive time: 872 ms rx bytes: 219111 rx packets: 1133 tx bytes: 53767 tx packets: 462 tx retries: 51 tx failed: 0 beacon loss: 0 beacon rx: 403 rx drop misc: 74 signal: -95 dBm beacon signal avg: -18 dBm tx bitrate: 1441.1 MBit/s 80MHz EHT-MCS 13 EHT-NSS 2 EHT-GI 0
