This is a note to let you know that I've just added the patch titled nfp: devlink: initialize the devlink port attribute "lanes" 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: nfp-devlink-initialize-the-devlink-port-attribute-la.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 71ffc2874b46441c624b509c4efb3089575bc729 Author: Yinjun Zhang <yinjun.zhang@xxxxxxxxxxxx> Date: Wed Apr 21 11:24:15 2021 +0200 nfp: devlink: initialize the devlink port attribute "lanes" [ Upstream commit 90b669d65d99a3ee6965275269967cdee4da106e ] The number of lanes of devlink port should be correctly initialized when registering the port, so that the input check when running "devlink port split <port> count <N>" can pass.
