It actually mostly obeys newbus at the moment.  Any places that may seem =
to be cutting corners are actually interfacing to lower-layers that =
don't participate in newbus (like if_media).  dcphy is also a little =
weird because it isn't really a PHY connected via a MII bus at all.  =
There may also be a few allowances made since it has been ported (and =
reported) to and from NetBSD and BSD/os a few times.
