From 59021c675995281d453eee45b3e2e1e3edbc0ec2 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Wed, 2 Mar 2016 23:28:32 +0200 Subject: mac80211: TDLS: change BW calculation for WIDER_BW peers The previous approach simply ignored chandef restrictions when calculating the appropriate peer BW for a WIDER_BW peer. This could result in a regulatory violation if both peers indicated 80MHz support, but the regdomain forbade it. Change the approach to setting a WIDER_BW peer's BW. Don't exempt it from the chandef width at first. If during TDLS negotiation the chandef width is upgraded, update the peer's BW to match.
