Does the rest of this work? You can actually transmit/receive frames,
but it is a 10/Half? So the MAC is working, just the PHY is missing?

If you look at dm9601_mdio_write() and dm9601_mdio_read() it always
passes 1. 0 is used for the EEPROM, at least in a real device. so try
1-31 and see if you get anything interesting.
