29-ATH11K_DBG_HTT_EXT_STATS_PEER_CTRL_PATH_TXRX_STATS:
Used to dump the control path txrx stats for each connected peer.
Usage:
echo 29 > /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/netdev\:wlan0/stations/
<sta mac>/htt_peer_stats.

31-ATH11K_DBG_HTT_EXT_STATS_PDEV_TX_RATE_TXBF_STATS:
Used to dump the per pdev tx rate txbf stats.
Usage:
echo 31 > /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats

32-ATH11k_DBG_HTT_EXT_STATS_TXBF_OFDMA:
Used to dump the TXBF ofdma stats for all ofdma users.
Usage:
echo 32 > /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats

37-ATH11K_DBG_HTT_EXT_PHY_COUNTERS_AND_PHY_STATS:
Used to dump the mac and phy txrx counts and phy stats like per chain rssi
and ANI level.
