From: Mohammed Shafi Shajakhan <mohammed@xxxxxxxxxxxxxxxx>
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'
