@Mohammed: Can you also test the official build and set the verification tag as appropriate per comment #18?

This prevents enablement and usage of HW offloads, such as TSO and checksumming for MPLS tagged traffic when running via VLAN or bonding interface. The patches introduce changes to the initialization steps of the VLAN and bonding netdevices to inherit the MPLS features from lower netdevices to allow the HW offloads. == Fix == * 5dc9520bf04a ("net/mlx5e: Report netdevice MPLS features") * 8b6912a50193 ("net: vlan: Inherit MPLS features from parent device") * 2e770b507ccd ("net: bonding: Inherit MPLS features from slave devices") * e4683f35f8e5 ("net/mlx5e: Move to HW checksumming advertising") The first two patches can be cherry-picked into Disco, and the rest will require some context adjustment. == Test == Test kernels can be found here: https://people.canonical.com/~phlin/kernel/lp-1851446-MPLS-0407/ Kernel tested with positive test result and approved by their QA. == Regression Potential == Low, changes just for adding MPLS feature and comes with positive test result. == Original Bug Report == Mellanox is requesting a backport of the following commit IDs from 5.3 back to 4.15.
