I see in the /management section it potentially can do other types, but
obviously ModemManager shouldn't be in the business of attempting to
modeswitch the device...  Since this thing has a fairly comprehensive
API, perhaps it should get controlled by ModemManager, probably with
some indication to the connection manager that the eth interface should
be started immediately so MM can then talk to it, then the connection
manager just gets a notification from MM when the connection is up or
down and can toggle default routes accordingly.  Another IpMethod value
for the bearer, and possibly another property for the Modem object
itself to indicate how to treat it.

At least they picked a subnet other than 192.168.0/24 or 192.168.1/24
this time.
