From f7917af92024d43bc20bc1afc92de27b0bd0f50b Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 27 Apr 2010 00:26:34 +0200 Subject: mac80211: fix handling of 4-address-mode in ieee80211_change_iface A misplaced interface type check bails out too early if the interface is not in monitor mode. This patch moves it to the right place, so that it only covers changes to the monitor flags. Signed-off-by: Felix Fietkau Cc: stable@kernel.org Signed-off-by: John W.
