Nikos Dragazis June 19, 2019, 3:14 p.m. UTC 
This patch propagates struct vhost_user_socket's vhost_transport_ops
into the newly created vhost device.

This patch completes the initial refactoring of socket.c, with the
AF_UNIX-specific code now in trans_af_unix.c and the librte_vhost API
entrypoints in socket.c.

Now it is time to turn towards vhost_user.c and its mixture of
vhost-user protocol processing and socket I/O.  The socket I/O will be
moved into trans_af_unix.c so that other transports can be added that
don't use file descriptors.
