If tx complete is not disabled, then firmware report the tx status and ath10k indicate the status to mac80211, then mac80211 save the statistics and command "iw wlan0 station dump" show them. for example: localhost ~ # iw dev wlan0 station dump Station 3c:28:6d:96:fd:69 (on wlan0) inactive time: 5 ms rx bytes: 1325012 rx packets: 6477 tx bytes: 85264 tx packets: 518 tx retries: 0 tx failed: 0 This patch only effect chips with tx complete disabled, e.g. SDIO. with this patch, output of command "iw dev wlan0 station dump": Station c4:04:15:5d:97:22 (on wlan0) inactive time: 608 ms rx bytes: 180366 rx packets: 991 tx bytes: 98765577 tx packets: 64624 tx retries: 14682 tx failed: 47086 Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.
