Added per tid sta counters for the following
- Total number MSDUs received from firmware
- Number of MSDUs received with errors like decryption, crc, mic ,etc.
- Number of MSDUs dropped in the driver
- A-MPDU/A-MSDU subframe stats
- Number of MSDUS passed to mac80211
All stats other than A-MPDU stats are only for received data frames.
A-MPDU stats might have stats for management frames when monitor
interface is active where management frames are notified both in wmi
and HTT interfaces.
These per tid stats can be enabled with tid bitmask through a debugfs
like below
echo <tid_bitmask> > /sys/kernel/debug/ieee80211/phyX/ath10k/sta_tid_stats_mask
tid 16 (tid_bitmask 0x10000) is used for non-qos data/management frames
The stats are read from
/sys/kernel/debug/ieee80211/phyX/netdev\:wlanX/stations/<sta_mac>/dump_tid_stats
Sample output:
To enable rx stats for tid 0, 5 and 6,
echo 0x00000061 > /sys/kernel/debug/ieee80211/phy0/ath10k/sta_tid_stats_mask
cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan15/stations/8c\:fd\:f0\:0a\:8e\:df/dump_tid_stats
