This patch series adds support to dump per station tx stats histogram.

These stats can be enabled through ath10k/enable_extd_tx_stats debugfs entry,
enabling this may impact in cpu usage and throughput.

ath10k/enable_extd_tx_stats is disabled by default.

Tx histogram has Per station tx stats which includes,
 - pkts/bytes transmitted at all possible rates(mcs/nss/bw/gi).
 - ACK fails count
 - ampdu bytes/pkts transmitted at all possible rates(mcs/nss/bw/gi).
 - BA fails count
 - tx duration

Tested on QCA9984/QCA4019/QCA988x
Firmware: 10.4-3.5.3-00057
	  10.2.4-1.0-00037

Example output format:
# cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan0/stations/8c\:
fd\:f0\:0a\:8c\:14/tx_stats

Anilkumar Kolli (4):
  ath10k: get the legacy rate index to update the txrate
  ath10k: add debugfs entry to enable extended tx stats
  ath10k: add extended per sta tx statistics
  ath10k: add debugfs support to dump per sta tx stats
