Subject: [PATCH v3 1/2] ath10k: Add support for ath10k_sta_statistics support

From: Mohammed Shafi Shajakhan <[email protected]>

Enable support for 'drv_sta_statistics' callback.
Export rx_duration support if available to cfg80211/nl80211

This can also act as a placeholder for any new per STA stats support

[v3] removed conditions for ath10k state checks based on Michal's suggestion

Dependencies:

1. cfg80211/nl80211: Add support for NL80211_STA_INFO_RX_DURATION (under review)
2. iw: Add support for NL80211_STA_INFO_RX_DURATION netlink
attribute (under review)
3. ath10k: Enable debugfs provision to enable Peer Stats feature (merged in pending branch)

Subject: [PATCH v3 2/2] ath10k: Remove debugfs support for Per STA total rx duration

From: Mohammed Shafi Shajakhan <[email protected]>

cfg80211/nl80211 interface changes for per STA total rx-duration and
very basic 'ath10k_sta_statistics' mac80211 callback is implemented
to extend support for per station statistics from the driver.

Also provision in 'iw dev wlan#N station dump' to parse rx-duration
is supported. So its safer to remove the debugfs entry for per STA
rx-duration

The dependency is in mac80211-next currently:

49da43f94f5e cfg80211/nl80211: Add support for NL80211_STA_INFO_RX_DURATION

(Sorry for the noise, I wish patchwork would have a feature to add
notes)
