It is not a NIC in the sense that you do TCP/IP over it. These
NICs with VIA support are used in high speed homogenous networks
between cluster nodes IIRC.
So it _is_ ok to work around all this networking code, because
they do DSHM and message passing with these networks in a very
homogenous manner.
Right Weimin?
