From c4d627dbe13fe5fe60e1c5515883236be424cec9 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov <arik@wizery.com> Date: Wed, 2 Mar 2016 23:28:31 +0200 Subject: [PATCH] mac80211: TDLS: always downgrade invalid chandefs 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.
