On a different note, I am not sure that using sysfs/kobject bus object
is the right thing for this object.  Isn't the phy instance really just
an kobject whose parent is the network device?  I can't see a 1 to N
relationship between phy bus and phy objects existing. 

The main use I can see for being a driver object is to catch suspend/resume,
and wouldn't you want that to be tied to the network device.
