When run command "iw dev wlan0 station dump", the rx duration is 0. When firmware indicate WMI_UPDATE_STATS_EVENTID, extended flag of statsis not set by default, so firmware do not report rx duration. one sample: localhost # iw wlan0 station dump Station c4:04:15:5d:97:22 (on wlan0) inactive time: 48 ms rx bytes: 21670 rx packets: 147 tx bytes: 11529 tx packets: 100 tx retries: 88 tx failed: 36 beacon loss: 1 beacon rx: 31 rx drop misc: 47 signal: -72 [-74, -75] dBm signal avg: -71 [-74, -75] dBm beacon signal avg: -71 dBm tx bitrate: 54.0 MBit/s MCS 3 40MHz rx bitrate: 1.0 MBit/s rx duration: 0 us This patch enable firmware's extened flag of stats by setting flag WMI_TLV_STAT_PEER_EXTD of ar->fw_stats_req_mask which is set in ath10k_core_init_firmware_features via WMI_REQUEST_STATS_CMDID. After apply this patch, rx duration show value with the command: Station c4:04:15:5d:97:22 (on wlan0) inactive time: 883 ms rx bytes: 44289 rx packets: 265 tx bytes: 10838 tx packets: 93 tx retries: 899 tx failed: 103 beacon loss: 0 beacon rx: 78 rx drop misc: 46 signal: -71 [-74, -76] dBm signal avg: -70 [-74, -76] dBm beacon signal avg: -70 dBm tx bitrate: 54.0 MBit/s MCS 3 40MHz rx bitrate: 1.0 MBit/s rx duration: 358004 us This patch do not have side effect for all chips, because function ath10k_debug_fw_stats_request is already exported to debugfs "fw_stats" and WMI_REQUEST_STATS_CMDID is safely sent after condition checked by ath10k_peer_stats_enabled in ath10k_sta_statistics. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.
