udp_tunnel: add the ability to hard-code IANA VXLAN
mlx5 has the IANA VXLAN port (4789) hard coded by the device, instead of being added dynamically when tunnels are created. To support this add a workaround flag to struct udp_tunnel_nic_info. Skipping updates for the port is fairly trivial, dumping the hard coded port via ethtool requires some code duplication. The port is not a part of any real table, we dump it in a special table which has no tunnel types supported and only one entry. This is the last known workaround / hack needed to convert all drivers to the new infra. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
