    Disable MDC/MDIO on 82580

    divram

      Hello,

      in our hardware Intel 82580 Ethernet controller connected via SGMII works with Marvell PHY 88E1112. But it expects MDC/MDIO to be connected. I need to get it to work without MDC/MDIO. I2C Enable is a bit in the EEPROM and I tried disabling it but it still tries to read the PHY through MDC/MDIO.

       

      How can I get it to work without MDC/MDIO access? 82580 is used with an I7 processor and we are running it with Linux
