-- CONFIG_ETHER_ON_FEC[12]
-		Define to enable FEC[12] on a 8xx series processor.
-
-- CONFIG_FEC[12]_PHY
-		Define to the hardcoded PHY address which corresponds

-			#define CONFIG_FEC1_PHY 4
-		means that the PHY with address 4 is connected to FEC1

-		When set to -1, means to probe for first available.

-- CONFIG_FEC[12]_PHY_NORXERR
-		The PHY does not have a RXERR line (RMII only).

 - CONFIG_RMII
 		Enable RMII mode for all FECs.
