mac80211: make ieee80211_find_sta per virtual interface
Since we have a TODO item to make all station management dependent on virtual interfaces, I figured I'd start with pushing such a change to drivers before more drivers start using the ieee80211_find_sta() API with a hw pointer and cause us grief later on. For now continue exporting the old API in form of ieee80211_find_sta_by_hw(), but discourage its use strongly. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
