This is a note to let you know that I've just added the patch titled net/mlx5e: Fix capability check for updating vnic env counters to the 5.15-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: net-mlx5e-fix-capability-check-for-updating-vnic-env.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit e046fe8ed5aff3e06d2fe0ba3e77eb6a8cd8eab4 Author: Gal Pressman <gal@xxxxxxxxxx> Date: Mon Jun 27 15:05:53 2022 +0300 net/mlx5e: Fix capability check for updating vnic env counters [ Upstream commit 452133dd580811f184e76b1402983182ee425298 ] The existing capability check for vnic env counters only checks for receive steering discards, although we need the counters update for the exposed internal queue oob counter as well. This could result in the latter counter not being updated correctly when the receive steering discards counter is not supported. Fix that by checking whether any counter is supported instead of only the steering counter capability.
