net/mlx5e: Properly set steering match levels for offloaded TC decap rules
The match level computed by the driver gets to be wrong for decap rules with wildcarded inner packet match such as: tc filter add dev vxlan_sys_4789 protocol all parent ffff: prio 2 flower enc_dst_ip 192.168.0.9 enc_key_id 100 enc_dst_port 4789 action tunnel_key unset action mirred egress redirect dev eth1 The FW errs for a missing matching meta-data indicator for the outer headers (where we do have a match), and a wrong matching meta-data indicator for the inner headers (where we don't have a match). Fix that by taking into account the matching on the tunnel info and relating the match level of the encapsulated packet to the firmware inner headers indicator in case of decap. As for vxlan we mandate a match on the tunnel udp dst port, and in general we practically madndate a match on the source or dest ip for any IP tunnel, the fix was done in a minimal manner around the tunnel match parsing code.
