[ Upstream commit 5e73276c814fc1a5a1bce6be743e1a07baa6d4bc ]
Currently, the receive rate of EHT of "iw dev xxx station dump" command always show an invalid value.
This is because ath12k does not pass information about the rx_status of EHT to mac80211. So, mac80211 not calculate the receive rate.
To address this issue, add logic for handling rx_status of EHT to the ath12k_dp_rx_h_rate() function.
After that, "iw dev xxx station dump" show the correct receive rate. Such as:
Station 00:03:7f:12:03:03 (on wlo1) inactive time: 48 ms rx bytes: 59226 rx packets: 320 tx bytes: 26556 tx packets: 191 tx retries: 99 tx failed: 0 beacon loss: 0 beacon rx: 79 rx drop misc: 68 signal: -95 dBm beacon signal avg: -20 dBm tx bitrate: 688.2 MBit/s 40MHz EHT-MCS 13 EHT-NSS 2 EHT-GI 0 tx duration: 0 us rx bitrate: 619.5 MBit/s 40MHz EHT-MCS 8 EHT-NSS 3 EHT-GI 0
This patch affects the station mode of WCN7850 and QCN9274.
