Subject: [PATCH v2 03/13] ath9k: queue null frames in case of MCC
Date: Fri, 27 Nov 2015 09:37:08 +0100 [thread overview]
Message-ID: <1448613438-5173-3-git-send-email-janusz.dziedzic@tieto.com> (raw)
In-Reply-To: <1448613438-5173-1-git-send-email-janusz.dziedzic@tieto.com>
While mac80211 using null frames when connection polling,
we should queue this frames while NOA could be there, and
AP, P2P_GO could be not present.
Without this patch, with no traffic we often saw disconnections
while we try to send nullfunc when AP/GO wasn't present.
