mac80211: insert AP sta entry after filling it
We never clearly defined the semantics of the sta_notify callback and it was originally posted for iwlwifi which still doesn't use it at all. With the recent HT rework ath9k started relying on it, but I made a mistake there in that I made ath9k assume the HT information has already been filled in at sta_notify time. This isn't a hard thing to do, so do it. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
