I am confused about the MDIO interface present in the DPAA Fman controller. If we use the internal MDIO interface for each MAC we access the MDIO registers of SERDES (with address 0) it reports the the AN as complete and link status as up after some time, even if no cable is attached to port. While if we use the external MDIO interface and access the PHY for same MAC (with address mentioned in schematics) 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?
