From: Mohammed Shafi Shajakhan <redacted> 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' Signed-off-by: Mohammed Shafi Shajakhan <redacted> --- nl80211.h | 3 +++ station.c | 5 +++++ 2 files changed, 8 insertions(+)
