This is a note to let you know that I've just added the patch titled wifi: mac80211: Drop support for TX push path to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: wifi-mac80211-drop-support-for-tx-push-path.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit adb14721fdbeeea2f258414083897f57b7bd0076 Author: Alexander Wetzel <alexander@xxxxxxxxxxxxxx> Date: Sun Oct 9 18:30:40 2022 +0200 wifi: mac80211: Drop support for TX push path [ Upstream commit 107395f9cf4419fa29b553a00872a27e579ae304 ] All drivers are now using mac80211 internal queues (iTXQs). Drop mac80211 internal support for the old push path.
