Both msg_zerocopy and udpgso_bench have udp zerocopy variants. Exercise these as part of the standard kselftest run. With udp, msg_zerocopy has no control channel. Ensure that the receiver exits after the sender by accounting for the initial delay in starting them (in msg_zerocopy.sh). Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.
