These stats can be enabled through ath10k/enable_extd_tx_stats debugfs entry, enabling this may impact in cpu usage and throughput. ath10k/enable_extd_tx_stats is disabled by default. Tx histogram has Per station tx stats which includes, - pkts/bytes transmitted at all possible rates(mcs/nss/bw/gi). - ACK fails count - ampdu bytes/pkts transmitted at all possible rates(mcs/nss/bw/gi). - BA fails count - tx duration Tested on QCA9984/QCA4019/QCA988x Firmware: 10.4-3.5.3-00057 10.2.4-1.0-00037 Example output format: # cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan0/stations/8c\: fd\:f0\:0a\:8c\:14/tx_stats succ_pkts VHT MCS packets 0 0 0 0 0 138 26 18 23 38747 HT MCS packets 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 BW packets (20,40,80,160 MHz) 41 337 38574 0 NSS packets (1x1,2x2,3x3,4x4) 38952 0 0 0 GI packets (LGI,SGI) 38 38914 legacy rate packets (1,2 ...
