Hi Florian
When i did the same for mv88e6xxx, i renamed _phy_ to _mdio_. That
keeps with the general pattern for other mdio drivers, making it clear
there can be something else than a phy on the bus.

I tried lots of different things with mv88e6xxx, including i think
this. The problem is full_name can be quite long, so it gets
truncated. And i often found two different mv88e6xxx ended up with
identical truncated names, since the unique part was getting
discarded.

So i ended up with this, which is 100% reliable.
