From 8d9e464a27e4afca4782a632f4bb18ea5e1eec5d Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Wed, 24 Sep 2014 11:48:16 +0530 Subject: [PATCH] ath9k: Fix offchannel queuing Clearing IEEE80211_TX_CTL_PS_RESPONSE in a frame that is not in the current context doesn't seem right. Instead make sure that we don't add such frames to the UAPSD queue by using a local variable. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
