From 5ed176e1c425f9bd1af161d66d348f6116a04fc6 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 4 Nov 2009 14:42:28 +0100 Subject: 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 Signed-off-by: John W.
