Currently, peer extended Rx statistics are not supported. Therefore, expose
peer extended Rx statistics support through debugfs, allowing users to
enable or disable the collection of statistics information. After that
the statistics information can be dumped through debugfs. Below are the
debugfs commands exposed.
Enable/Disable:
echo <1/0> > /sys/kernel/debug/ieee80211/phyX/ath12k/ext_rx_stats
Dump:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/<peer MAC addr>/rx_stats
