From: Nick Hawkins <nick.hawkins@xxxxxxx> The GXP contains two Ethernet MACs that can be connected externally to several physical devices. From an external interface perspective the BMC provides two SERDES interface connections capable of either SGMII or 1000Base-X operation. The BMC also provides a RMII interface for sideband connections to external Ethernet controllers. The primary MAC (umac0) can be mapped to either SGMII/1000-BaseX SERDES interface. The secondary MAC (umac1) can be mapped to only the second SGMII/1000-Base X Serdes interface or it can be mapped for RMII sideband. The MDIO(mdio0) interface from the primary MAC (umac0) is used for external PHY status and configuration. The MDIO(mdio1) interface from the secondary MAC (umac1) is routed to the SGMII/100Base-X IP blocks on the two SERDES interface connections.
