(for clarity, rather than as an argument against this idea)
This isn't how -net works : "-net nic,options" sets up an
entry in the nd_table[], and the board will then pick up those
entries based on some ad-hoc combination of order and whether
a model= was specified for that nic.

How would this work for (for example) specifying a macaddr
for the built-in NIC? At the moment you can do that with
-net nic,macaddr=<whatever>.
