From ec2b774e7c91094d8c00de579646f1162b87b01e Mon Sep 17 00:00:00 2001 From: Marek Lindner Date: Tue, 20 Dec 2011 23:16:52 +0800 Subject: [PATCH] mac80211: ibss should not purge clients it is not responsible for The IBSS merge code calls ieee80211_sta_expire() with a relatively short expire timeout that purges other clients prematurely. The expire function has to check that only the clients belonging to the vif in question are purged. Signed-off-by: Marek Lindner Signed-off-by: John W.
