Hi,
I apologize for the delay in responding.
actually we tested the patches and it seems that some functionality of
the features is not working as expected in Bionic/Eoan Kernels.
there is no TSO over MPLS traffic and that because of missing the following
upstream patch:
- e4683f35f8e5 ("net/mlx5e: Move to HW checksumming advertising").
so we need also this patch to be able to use TSO for MPLS traffic.
if you please can backport it that will be great. and please let us know
if you need any assistance.
Regards,
Mohammad

Title:
Backport MPLS patches from 5.3 to 4.15
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Bionic:

Bug description:
Mellanox is requesting a backport of the following commit IDs from 5.3
back to 4.15.
Netdevice HW MPLS features are not passed from device driver's
netdevice to upper netdevice, specifically VLAN and bonding netdevice
which are created by the kernel when needed.
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.
