From f1e3be1561c43b6bbe2426e34849fb1486dc313b Mon Sep 17 00:00:00 2001 From: Nicolas Cavallari Date: Thu, 26 Jan 2012 13:36:34 +0100 Subject: [PATCH] mac80211: Do not scan for IBSS merge with a fixed BSSID. Currently, when we are on an IBSS network with no active station, we would scan for other BSSID, even if fixed_bssid is on, due to a bug in ibss.c, where fixed_channel would be checked instead of fixed_bssid. This would trigger useless scans where scan results would not be used anyway. This patch also reverts commit 39d02a7d90602d4557ee05db2a157a4e0, which assumed that the ifibss->fixed_channel check was legitimate to disable single-channel scans. IBSS single-channel scan should now be fixed. Signed-off-by: Nicolas Cavallari Signed-off-by: John W.
