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.
