This is a note to let you know that I've just added the patch titled net/mlx5e: Fix features validation check for tunneled UDP (non-VXLAN) packets to the 6.1-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-features-validation-check-for-tunneled.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit dc27cb0512dbd53bd3b0817f11aea9b90d85ad6e Author: Gal Pressman <gal@xxxxxxxxxx> Date: Thu Jun 6 23:32:49 2024 +0300 net/mlx5e: Fix features validation check for tunneled UDP (non-VXLAN) packets [ Upstream commit 791b4089e326271424b78f2fae778b20e53d071b ] Move the vxlan_features_check() call to after we verified the packet is a tunneled VXLAN packet. Without this, tunneled UDP non-VXLAN packets (for ex. GENENVE) might wrongly not get offloaded. In some cases, it worked by chance as GENEVE header is the same size as VXLAN, but it is obviously incorrect.
