Currently, the signal strength of "iw dev xxx station dump" always show an invalid value. This is because signal strength is only set in ath12k_mgmt_rx_event() function, and not set for received data packet. So, change to get signal from firmware and report to mac80211. After that, "iw dev xxx station dump" show the correct signal strength. Such as: Station 00:03:7f:12:03:03 (on wlo1) inactive time: 36 ms rx bytes: 61571 rx packets: 336 tx bytes: 28204 tx packets: 205 tx retries: 49 tx failed: 0 beacon loss: 0 beacon rx: 83 rx drop misc: 66 signal: -24 dBm beacon signal avg: -22 dBm For WCN7850, the firmware supports db2dbm, so not need to add noise floor. For QCN9274, the firmware not support db2dbm, so need to add noise floor. This patch affects the station mode of WCN7850 and QCN9274.
