[PATCH v2] iw: Add support for NL80211_STA_INFO_RX_DURATION netlink attribute

2016-03-09 Thread Mohammed Shafi Shajakhan 
From: Mohammed Shafi Shajakhan 

Enable support for parsing per station rx-duration (usecs)
via adding support for new netlink attribute NL80211_STA_INFO_RX_DURATION

rx_duration is aggregate PPDU duration(usecs) for all the frames
frames from a peer . This will get dumped as part of
'iw dev wlan#N station dump'

[PATCH v2] iw: Add support for NL80211_STA_INFO_RX_DURATION netlink attribute

2016-03-08 Thread Mohammed Shafi Shajakhan 
From: Mohammed Shafi Shajakhan 

Enable support for parsing per station rx-duration (usecs)
via adding support for new netlink attribute NL80211_STA_INFO_RX_DURATION

rx_duration is an approximate total air time(usecs) for all the frames
frames from a connected client. This will get dumped as
part of 'iw dev wlan#N station dump'
