From 2a5783b817c90ce6fb82a21e103335d1ecbac430 Mon Sep 17 00:00:00 2001 From: Michael Liang Date: Fri, 20 Apr 2012 17:11:57 +0800 Subject: [PATCH] ath9k: don't strip mic on non-encrypted frames in tkip Fix the following bug: in tkip mode, qos-null ps on/off packets are dropped due to incorrect packet length so that ath9k softap can't handle powersave state transition of peer STA correctly.
