From 4aff53ef18e4a444dea060ab5d25128f87093d54 Mon Sep 17 00:00:00 2001 From: Xinming Hu Date: Mon, 4 May 2015 22:10:08 +0530 Subject: [PATCH] mwifiex: parsing aid while receiving association response cfg80211 would complain about invalid AID in during TDLS setup. This was happening because we use same AID value as provide by AP while forming setup messages. Parse AID from Association response and filter BIT14 and BIT15 of AID to get valid AID.
