enetc#0
is 1G SGMII port of ENETC.

enetc#1
is presented in U-Boot on all boards. This interface is not
functional on RDB.
Internal
enetc#2
0000:00:00.2
Connected internally (MAC to MAC) to the Ethernet switch. Note
that the switch is not initialized in U-Boot; therefore, this interface
is not functional.
Internal
enetc#3
0000:00:00.6
Connected internally (MAC to MAC) to the Ethernet switch. This
interface is presented if bit 851 is set in RCW. Note that the switch
is not initialized in u-boot; therefore, this interface is not functional.
1G SWP0 to
1G SWP3
N/A
0000:00:00.5
The switch is currently not initialized by U-Boot; therefore, these
interfaces are not functional.
