In our custom board, we have connected four sgmii ports to an Marvel switch. The switch is capable of performing auto negotiation. We are selecting the SGMII configuration in RCW. Will the eMAC does default auto negotiation with the switch or do i need to perform any configurations for SGMII serdes or eMAC to establish the gigabit link with switch. If so, how to configure the eMAC.

FM2 EMI1(MDIO) is used to configure the Ethernet switch. Each eMAC is having an MDIO. When this eMAC MDIO will be used. Do i need to use this MDIO to configure the SGMII which is connected to the ethernet switch.
