Subject: [PATCH 1/3] mac80211: TDLS: always downgrade invalid chandefs
Date: Wed,  2 Mar 2016 23:28:31 +0200	[thread overview]
Message-ID: <1456954113-4682-1-git-send-email-emmanuel.grumbach@intel.com> (raw)

From: Arik Nemtsov <arik@wizery.com>

Even if the current chandef width is equal to the station's max-BW, it
doesn't mean it's a valid width for TDLS. Make sure to always check
regulatory constraints in these cases.

Fixes: dde4002 ("mac80211: upgrade BW of TDLS peers when possible")
