Yes, FMan microcode is required for FMan Independent mode.

Thanks Paton. One more thing I am confused about is the MDIO interface present in the Fman controller. If we use the internal MDIO interface for each MAC we access the MDIO registers of SERDES which automatically reports the the AN as complete and link status as up, even if no cable is attached to port. While if we use the external MDIO interface and access the PHY for same MAC then we access the standard PHY register which reports correct link and auto negotiation status. So what link status are the SERDES MDIO registers referring to?
