+ * The 10Gb XGMII PHY is provided via the XAUI riser card. There is only
+ * one Fman device on B4860. The SERDES configuration is used to determine

+ * to which PHYs. So for a given Fman MAC, there is one and only PHY it
+ * connects to. MACs cannot be routed to PHYs dynamically. This configuration
