We do look at the 'type' field, to determine how to connect up the
backend to a physical device.

"type=ioemu" and "type=netfront" both behave similarly to the Linux
code ("netfront" creates a pseudo-ethernet device that could be used
by IP or a bridge, "ioemu" prompts qemu-dm to do the right thing
(which is different on Solaris, but anyway)).

"type=SUNW_mac", the default on Solaris (well, previously the
default), results in different approach where we expect to open a
physical or pseudo-physical device directly and relay
packets. Typically it's a pseudo-physical device created by the
hotplug scripts using Crossbow[1] VNICs.

I'll look at the changes more closely and figure out what to do.
