This is a note to let you know that I've just added the patch titled wifi: ath12k: Optimize the mac80211 hw data access to the 6.6-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-ath12k-optimize-the-mac80211-hw-data-access.patch and it can be found in the queue-6.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a28acaad2f30e25e035925efd0472f3cb62d7c9f Author: Karthikeyan Periyasamy <quic_periyasa@xxxxxxxxxxx> Date: Tue Nov 21 05:28:11 2023 +0530 wifi: ath12k: Optimize the mac80211 hw data access [ Upstream commit 842addae02089fce4731be1c8d7d539449d4d009 ] Currently mac80211 hw data is accessed by convert the hw to radio (ar) structure and then radio to hw structure which is not necessary in some places where mac80211 hw data is already present. So in that kind of places avoid the conversion and directly access the mac80211 hw data.
