This is duplicating uAPI. Hi Jakub, So far the only way to dump the XDP features supported by the NIC is through libbpf running bpf_xdp_query(). I would say it is handy for a sysadmin to examine the XDP NIC capabilities in a similar way he/she is currently doing for the hw offload capabilities. Something like (I have an ethtool user-space patch not posted yet): $ethtool --get-xdp-features eth0 XDP features for eth0: xdp-basic: supported xdp-redirect: supported xdp-ndo-xmit: supported xdp-xsk-zerocopy: not-supported xdp-hw-offload: not-supported xdp-rx-sg: not-supported xdp-ndo-xmit-sg: not-supported Regards, Lorenzo
