Subject: [PATCHv3] mac80211: Use appropriate TID for sending BAR, ADDBA and DELBA frames
Date: Thu, 15 Dec 2011 10:18:34 +0100 [thread overview]
Message-ID: <1323940714-20235-1-git-send-email-helmut.schaa@googlemail.com> (raw)
In-Reply-To: <1323936138-11357-1-git-send-email-helmut.schaa@googlemail.com>
Currently BAR, ADDBA and DELBA frames are always sent using AC_VO. If
the TID for which a BA session is established is assigned to a different
queue BAR, ADDBA and DELBA frames can "overtake" frames of the according
BA session.
Hence, always put BA session related frames into the same queue as the
BA sessions data frames.
