Xen used to have ethernet drivers built into the hypervisor itself in the 1.x
series, but this got dropped since the Xen 2 release. I'd have thought it'd
be somewhat undesirable to try to put this back in there... Especially since
a load of the PCI code has moved to dom0 as well now.
What are you actually trying to achieve? Are you sure you can't do this from
dom0? e.g. run a daemon in each dom0 communicating with Xen by hypercalls or
ring buffers, and then use normal Linux networking? I'd have thought that'd
be a cleaner solution too.
Of course, what is best does rather depend on what you're trying to do ;-)

You could take a look at some of the older releases of Xen to see how PCI and
network code used to be part of the hypervisor. I'd recommend avoiding doing
that though!
