Based on hardware information from Linux l1 driver I wrote a simple
PHY driver. You can get the diff at the following URL.
Would you give it spin?

http://people.freebsd.org/~yongari/atphy.diff

Note, I don't have the hardware so don't know whether it works or
not. Just compile tested. I also have no PHY hardware information
so the model name in the driver may not reflect real name.
