Is it possible to use recvmsg/read on an AF_XDP socket? I've been able
to set up a socket, write an XDP program, and properly receive frames
in UMEM with the RX and Fill rings, but am more interested in using
standard linux C functions. Some libxdp documentation mentions the use
of poll and sendto/recvmsg, and I have successfully polled the socket
(as one would a normal AF_INET socket), but can't find documentation
on clearing the revents status after a poll. Any help or redirection
to documentation would be appreciated.
