nfp: flower: compile Geneve match fields
Compile Geneve match fields for offloading to the NFP. The addition of Geneve overflows the 8 bit key_layer field, so apply extended metadata to the match cmsg allowing up to 32 more key_layer fields. Rather than adding new Geneve blocks, move the vxlan code to generic ipv4 udp tunnel structs and use these for both vxlan and Geneve. Matches are only supported when specifically mentioning well known port 6081. Geneve tunnel options are not yet included in the match. Only offload Geneve if the fw supports it - include check for this.
