   4 Subject: [PATCH] wifi: ath11k: Add HTT stats for PHY reset case
   5
   6 New HTT stats are added with stats type 37 to
   7 provide PHY reset stats and PHY reset counter stats.
   8
   9 PHY reset stats are used to display the current
  10 PHY-related operation information such as band, CCA
  11 threshold, current operating channel etc.,
  12
  13 PHY reset counter stats are used to display the
  14 PHY reset counter values like calibration counts,
  15 temperature based recalibration counts etc.,
  16
  17 Usage:
  18 echo 37 > /sys/kernel/debug/ieee80211/phyX/ath11k/htt_stats_type
  19 cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats
