Subject: [PATCH v3 RESEND 1/2] ath10k: Add support for ath10k_sta_statistics support
Date: Mon, 2 May 2016 21:22:27 +0530	[thread overview]
Message-ID: <1462204347-31012-1-git-send-email-mohammed@qca.qualcomm.com> (raw)

From: Mohammed Shafi Shajakhan <mohammed@qti.qualcomm.com>

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 <mohammed@qti.qualcomm.com>
---
[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)
