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.
