So you would have each PHY know the controller to which it's attached?  
I would have thought the other way around... Hm.  I will definitely 
have to read up on my driver model stuff

I think you misunderstood.  Are you talking about sysfs?  I was talking 
about actual source files.  i.e. should there be dm9161.c, m88e1101.c, 
cis8201.c, etc.

Also, do we need user-space to read/write PHY registers.  ethtool has 
this capability, I believe, and the interfaces there are settled.
