From 3edaf3e61fda3aa9ff8d38445bf92f2bec23bf63 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 3 Apr 2012 10:24:00 +0200 Subject: [PATCH] mac80211: manage AP netdev carrier state The AP netdev is really only active when beaconing, so manage the carrier state accordingly. Also do that for VLAN interfaces enslaved to a given AP interface. Signed-off-by: Johannes Berg Signed-off-by: John W.
