From c72e1140463a643579c3f9e09f990e71e95671ac Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Thu, 17 Jul 2014 17:14:29 +0300 Subject: [PATCH] cfg80211: fix TDLS setup with VHT peers Some VHT TDLS peers (Google Nexus 5) include the VHT-AID IE in their TDLS setup request/response. Usermode passes this aid as the station aid, causing it to fail verifiction, since this happens in the "set_station" stage. Make an exception for the TDLS use-case.
