From: Mohammed Shafi Shajakhan <[email protected]>
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'
