Oh, I think genphy is just a generic driver, but his layer has hooks for
other PHY drivers (wasn't it based on sungem_phy in the first place ?)
I discussed several steps of the design with Andy, the idea was to have
something a bit like sungem_phy.c with addditional common library for
doing the link polling & fallback stuff etc... that could be easily
shared by drivers.
