Hi Joakim,

I'm wondering if we really need to have the option to disable phylib.
Actually we have made phylib selected by default for ucc_geth.  Many L2
switch chips have the capacity to be controlled.  Therefore they can be
managed as a phy device.  For the MII interface which is not
configurable, shouldn't we use the fixed phy support from Vitaly?
