net/mlx5e: Properly handle offloading of source udp port for IP tunnels
We can offload the matching on source udp port of ip tunnels for decapsulation. We can not offload setting source udp port for tunnels as part of encapsulation. Fix both the code that deals with matching offload (decap) and the code that deal with encap offload to align with that. Fixes: a54e20b4fcae ('net/mlx5e: Add basic TC tunnel set action for SRIOV offloads') Fixes: bbd00f7e2349 ('net/mlx5e: Add TC tunnel release action for SRIOV offloads') Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Reviewed-by: Hadar Hen Zion <hadarh@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.
