net/mlx5: support UDP tunnel adding
This adds support for adding a new UDP tunnel port on a specific VXLAN types. Currently we only support VXLAN, VXLAN-GPE on ports 4789, 4790 respectively. Without having to configure anything in the NIC. Signed-off-by: Raslan Darawsheh <rasland@mellanox.com> Acked-by: Viacheslav Ovsiienko <viacheslavo@mellanox.com>
