From 84a3d1c97d024acd1d27ebbc10cb95784b11f4e7 Mon Sep 17 00:00:00 2001 From: Janusz Dziedzic Date: Tue, 5 Nov 2013 14:48:46 +0100 Subject: [PATCH] mac80211: DFS setup chandef for radar_event correctly Setup chandef for radar event correctly, before we will clear this in ieee80211_dfs_cac_cancel() function. Without this patch mac80211 will report wrong channel width in case we will get radar event during active CAC. Signed-off-by: Janusz Dziedzic Reviewed-by: Luis R.
