From f3740572512075839e1a7ebde970081106fed3f0 Mon Sep 17 00:00:00 2001 From: Vivek Natarajan Date: Wed, 2 May 2012 14:55:25 +0530 Subject: [PATCH] ath6kl_sdio: Fix the EAPOL out of order issue Send the EAPOL and management frames in the same AC_VO queue. The issue happens when the AP supports QOS, the management frames are sent to AC_VO queue and EAP frame goes to AC_BE queue. Even though the EAP frame is queued before the DEAUTH management frame, as they are queued on different h/w queues, order of delivery between these frames cannot be controlled. This fixes the connection failure seen in P2P case.
