Freescale's T1040qds board may be configured to have up to 5 FMAN ports (FM1@DTSEC1 to FM1@DTSEC5). From these 5 ports, 2 of them may be fixed-links (FM1@DTSEC1 annd FM1@DTSEC2), connected to other two ports from an intergrated VSC9953 L2 Switch (switch ports 8 and 9). These fixed-link ports have no PHYs attatched, so they don't have a corresponding MDIO.
