Linville" Subject: [ 18/82] mac80211: fix ADDBA declined after suspend with wowlan In-Reply-To: <20120607041406.GA13233@kroah.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: 3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Eyal Shapira commit 7b21aea04d084916ac4e0e8852dcc9cd60ec0d1d upstream. WLAN_STA_BLOCK_BA is set while suspending but doesn't get cleared when resuming in case of wowlan. This causes further ADDBA requests received to be rejected. Fix it by clearing it in the wowlan path as well. Signed-off-by: Eyal Shapira Reviewed-by: Johannes Berg Signed-off-by: John W.
