Post a link to the board you have. Most of the Altera kits I have use a Marvell 88E1111 with a PHY address of 0, using MDIO mode for the communications interface.

For a PHY address of zero, config[0] = GND, and config[1] = LED_LINK1000.

If your board has this PHY, but a different connection, respond with the link and I'll look in the PHY data sheet to tell you what the address is.
