Hi All,
I see that GENEVE tunnel type is currently not supported in
i40e_dev_udp_tunnel_port_add(). Is there any reason for this or a roadmap
for when this is planned to be done? I looked into the latest DPDK (24.03)
and it is still not available there.
I'm using XXV710 with an i40e driver and want to associate UDP port 6081 as
a GENEVE tunnel on all ports so that RSS works correctly and distributes
traffic based on inner packets. I checked the XXV710 datasheet and found
that the following patch works for me, but I would like someone else
familiar with this to take a look at it.
