[U-Boot] Help Needed - Realtek 8100B (8139) Ethernet not working

[Graeme Russ]

Hi All,

I'm having real trouble getting the two RTL8100B Ethernet chips working on
my board. I can probe them, but not much else. The strange thing is, on
first bootup, it complains about SROM address not matching environment
address which goes away after a soft reset. However, whenever I try to
execute a network command, it always complains about missing Ethernet
addresses.

I've enabled RX and TX debugging, and this is the end result of my efforts:
