This patch is needed if the MAC is directly connected to a ethernet switch. In my case the FEC MAC is connected to a Micrel KSZ8895. All I need to to is configure my fixed phy/link like:

#define IMX_FEC_BASE ENET_BASE_ADDR #define CONFIG_FEC_XCV_TYPE MII100 #define CONFIG_ETHPRIME "FEC" #define CONFIG_FEC_MXC_PHYADDR 0x5 #define CONFIG_PHYLIB #define CONFIG_PHY_FIXED #define CONFIG_PHY_FIXED_SPEED SPEED_100 #define CONFIG_PHY_FIXED_DUPLEX DUPLEX_FULL
