[PATCH] wifi: ath11k: support HTT extended receive rate debug stats

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



ATH11K_DBG_HTT_EXT_STATS_PDEV_RX_RATE_EXT  =  30

HTT stats, HTT_RX_PDEV_RATE_EXT_STATS has the rx stats info of
the extended 80MHz, mainly 80+80 and 160MHz modes.

Usage:
echo 30 > /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats
