This is a note to let you know that I've just added the patch titled wcn36xx: fix RX BD rate mapping for 5GHz legacy rates to the 5.10-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: wcn36xx-fix-rx-bd-rate-mapping-for-5ghz-legacy-rates.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit fac6d17e7d9d29bbf5f6dc0f83ee4c08c4c9cc1a Author: Benjamin Li <benl@xxxxxxxxxxxx> Date: Wed Nov 3 18:05:48 2021 -0700 wcn36xx: fix RX BD rate mapping for 5GHz legacy rates [ Upstream commit cfdf6b19e750f7de8ae71a26932f63b52e3bf74c ] The linear mapping between the BD rate field and the driver's 5GHz legacy rates table (wcn_5ghz_rates) does not only apply for the latter four rates -- it applies to all eight rates.
