Subject: net/mlx5e: Support partial GSO for tunnels over vlans
Patch-mainline: v5.19-rc1
Git-commit: 682adfa6ca80f86dcdc5cebe85b11d30d15944d9
References: jsc#PED-1549
Offloading outer checksum on tunnels requires GSO partial, add it to
'vlan_features' to allow offloading tunnels over vlans.
For example, running GENEVE over vlan & ipv6 (mandatory UDP checksum)
now allows for hardware TSO instead of software segmentation in GSO
only.
