Subject: [PATCH v4 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

Signed-off-by: Mohammed Shafi Shajakhan <[email protected]>

[v4] rebased over 'pending' branch
[v3] removed conditions for ath10k state checks based on Michal's suggestion

Both the dependent changes are merged now in master tree

1. cfg80211/nl80211: Add support for NL80211_STA_INFO_RX_DURATION
2. iw: Add support for NL80211_STA_INFO_RX_DURATION netlink

But these are not in ath-next branch yet, so I can't take these until I
have updated ath-next.

Also please ping instead of resending patches. These are already waiting
in patchwork:

branch next time i will do this

a) ping you first
b) if required send a rebased version

Subject: [PATCH v4 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
