They are looking for and attempting to initialize the Ethernet PHY chip
(Ethernet generally comes with a MAC chip combined with a PHY chip).

There is an IEEE standardized set of registers that PHY chips should
implement that cover 99.9% of PHY operation.

The source code is available here:

Subject: MDI_FindPhy and MDI_InitPhy

Can anyone tell me what these APIs are doing specifically? Which device
addresses do they search? What do they look for being returned? My call
to FindPhy fails but my InitPhy succeeds. The driver on the whole does
not work. I am trying to drive a Marvell 88E6060 chip and the registers
may be a little non-standard so I'm not sure if the MDI_xxx calls are
working correctly. How can I write my own? Can I see the source code for
them? Thanks.
