There is a testpmd command to configure the NIC for GENEVE port,
"port config (port_id) udp_tunnel_port add|rm vxlan|geneve|vxlan-gpe (udp_port)"

You are adding support to testpmd to parse the GENEVE packets, but I think these 
two commads should be consistent.

What do you think "port config N add geneve X" update the 'geneve_udp_port=X"?

Can you please update the "csum parse-tunnel" documentation to mention "geneve" 
protocol?
