I agree with Jakub. I don't see how extra ethtool reporting will help.
Anyone who wants to know whether eth0 supports XDP_REDIRECT can already do so:
ethtool -S eth0 | grep xdp_redirect
I think converging on the same stat names across the drivers will make
the whole thing much more user friendly than new apis.
