[RFC] Netkit cannot be an XDP_REDIRECT target ?

Hi, When looking at netkit papers, one tends to view it as a kind of veth, rewritten for efficiency. However, the feature flags of a netkit never contain NETDEV_XDP_ACT_NDO_XMIT. In other words, it can never be an XDP_REDIRECT target. By contrast, xdp-redirecting to a veth works. This means that netkit is far from being a "drop-in" replacement for veth "just faster". It rather sounds like unfinished work. What am I missing here ? Is there another method to pass frames from the XDP RX hook of an interface to a netkit's ring ? Is netkit "here to stay", being actively worked on ? Or is it a single-purpose experiment that will never try to reach veth's functional coverage ? Thanks for any clarifications. -Alex
