This is a note to let you know that I have just added a patch titled ath9k: declare required extra tx headroom to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt20. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 6c4f89b8b9a5ab053c2d517ac1a987872f5ab9fe Mon Sep 17 00:00:00 2001 From: Felix Fietkau <nbd@openwrt.org> Date: Thu, 24 Sep 2015 16:59:46 +0200 Subject: ath9k: declare required extra tx headroom commit 029cd0370241641eb70235d205aa0b90c84dce44 upstream. ath9k inserts padding between the 802.11 header and the data area (to align it). Since it didn't declare this extra required headroom, this led to some nasty issues like randomly dropped packets in some setups.
