nfp: flower: offload tos and tunnel flags for ipv4 udp tunnels
Extract the tos and the tunnel flags from the tunnel key and offload these action fields. Only the checksum and tunnel key flags are implemented in fw so reject offloads of other flags. The tunnel key flag is always considered set in the fw so enforce that it is set in the rule. Note that the compulsory setting of the tunnel key flag and optional setting of checksum is inline with how tc currently generates ipv4 udp tunnel actions.
