Usually we require a driver to implement all the XDP return codes,
before we accept it. But as Daniel and I discussed with Zorik during
NetConf[1], we are going to make an exception and accept the driver
if you also implement XDP_TX.
As we trust that Zorik/Amazon will follow and implement XDP_REDIRECT
later, given he/you wants AF_XDP support which requires XDP_REDIRECT.
Jesper, thanks for your comments and very helpful discussion during NetConf!
That's the plan, as we agreed. From our side I would like to reiterate again
the
importance of multi-buffer support by xdp frame. We would really prefer not
to see our MTU shrinking because of xdp support.
