Once device does not support these, the l3fwd-power will exit and report an error. Maxime suggested to update the port configuration based on its capabilities. For RSS, it would be something like what I proposed for OVS: https://patchwork.ozlabs.org/project/openvswitch/patch/20210830101304.13689-1-david.marchand@redhat.com/ As for IPv4/UDP/TCP rx checksums, I am not sure there is any actual requirement for this app. Probably something to investigate wrt DO_RFC_1812_CHECKS. -- David Marchand
