From 53d69c399abf3b382c1e737ff9402d31ca5a7a51 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Mon, 12 Dec 2011 15:30:04 +0200 Subject: mac80211: don't check sdata_running in vif notifier The ip address of the vif can be set even before the vif is up. requiring the vif to be up in the vif notifier makes the notifer ignore this event, which causes wrong arp filter configuration later on.
