From 64f851e410ae37a0990212ae34f0c96b641478f7 Mon Sep 17 00:00:00 2001 From: Jan Niehusmann Date: Sun, 23 Mar 2008 20:23:56 +0100 Subject: [PATCH] mac80211: trigger ieee80211_sta_work after opening interface ieee80211_sta_work is disabled while network interface is down. Therefore, if you configure wireless parameters before bringing the interface up, these configurations are not yet effective and association fails. A workaround from userspace is calling a command like 'iwconfig wlan0 ap any' after the interface is brought up. To fix this behaviour, trigger execution of ieee80211_sta_work from ieee80211_open when in STA or IBSS mode. Signed-off-by: Jan Niehusmann Signed-off-by: John W.
