Subject: [PATCH] mac80211: fix AP buffered multicast frames with queue control and txq
Date: Sun, 28 Feb 2016 15:19:53 +0100	[thread overview]
Message-ID: <1456669193-56860-1-git-send-email-nbd@openwrt.org> (raw)

Buffered multicast frames must be passed to the driver directly via
drv_tx instead of going through the txq, otherwise they cannot easily be
scheduled to be sent after DTIM.
