The online manual for the 8255x parts is not adequate for driver
development. There are a signficant number of critical items missing from
it which would preclude you developing a driver based on the information
it contains; this datasheet has been available in one form or another for
some time and is generally regarded as almost useless.

The source-available Intel driver does actually look pretty good. I
don't know why David has failed to track it wrt. PHY numbers. I've
dumped the last board I had with an unrecognised PHY, so I don't have any
incentive to poke him about it anymore.
