Does this mean that the box doesn't boot correctly, or just that the
network card is not working when running under Xen?

The best option would be to hook a serial cable and get the output
from the serial console.

The list of valid xen_cmdline can be found here for the 4.11 ports:

Or here if you are using the 4.7 port:

You don't have to build a specific kernel to run FreeBSD as Dom0, just
using the GENERIC one from either 11.X or HEAD should work.
