Not yet, but I'll take this up for V2, after the merge window...

Thinking about MII, it really is a 1:1 connection between the MAC and
the PHY.  It has no representation in the current code, at least not
yet.  It is too bad about the naming of mii_bus, oh well.  While
hanging this thing off of the PHY isn't really great modeling (it
isn't a sub-device of the PHY in any sense), still this will work well
enough to enable the new functionality.

Thanks,
Richard
