Yes, but to be perfectly honest. I thought I was going to need
documentation on the isolation transformers as well. Pointyhat for

The KS8695 does have an external PHY, but, according to a datasheet on
the technical differences between the KS8695 and KS8695X I'm reading
atm, this is now optional. Performance wise, would it be ideal to
remove support, by disconnecting the pins for EMAC MII?
If so, it might be easier to port the KS8695X rather than the KS8695.
I think I would have to remain backwards compatible due to the
difference in voltages, and PHY enhancements though... Not sure on that
