+- CFG_RX_ETH_BUFFER:
+		Defines the number of ethernet receive buffers. On some
+		ethernet controllers it is recommended to set this value
+		to 8 or even higher (EEPRO100 or 405 EMAC), since all
+		buffers can be full shortly after enabling the interface

 The following definitions that deal with the placement and management
 of environment data (variable area); in general, we support the
 following configurations:
