Netfront driver can be also useful in dom0, eg when all NICs are assigned to
some domU (aka driver domain). Then using netback in domU and netfront in dom0
is the only way to get network access in dom0.

Someone please review this and I can merge it in via the 'net' tree if
it looks OK to XEN folks.
