This is a note to let you know that I've just added the patch titled wifi: mt76: mt7915: also MT7981 is 3T3R but nss2 on 5 GHz band to the 6.7-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-mt76-mt7915-also-mt7981-is-3t3r-but-nss2-on-5-g.patch and it can be found in the queue-6.7 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 71e017b17958bda71ff2dd511bbb062686a69862 Author: StanleyYP Wang <StanleyYP.Wang@xxxxxxxxxxxx> Date: Mon Nov 6 22:39:31 2023 +0000 wifi: mt76: mt7915: also MT7981 is 3T3R but nss2 on 5 GHz band [ Upstream commit ff434cc129d6907e6dbc89dd0ebc59fd3646d4c2 ] Just like MT7916 also MT7981 can handle 3T3R DBDC frontend and should hence be included in the corresponding conditional expression in the driver. Add it.
