This is a note to let you know that I have just added a patch titled ath9k: fix ready time of the multicast buffer queue to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.22. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 0aa129c5bcafdad84ac992d35831a23e47178500 Mon Sep 17 00:00:00 2001 From: Felix Fietkau <nbd@openwrt.org> Date: Sun, 9 Mar 2014 11:02:54 +0100 Subject: ath9k: fix ready time of the multicast buffer queue commit 3b3e0efb5c72c4fc940af50b33626b8a78a907dc upstream. qi->tqi_readyTime is written directly to registers that expect microseconds as unit instead of TU. When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so convert it to microseconds before passing it to ath9k_hw. This should hopefully fix some Tx DMA issues with buffered multicast frames in AP mode. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
