This is a problem I've been fighting to for a long time. I'm sure it would be something stupid I haven't noticed, but I don't know what else to try. My Linux OS is working flawlessly with a correct eth0 device, so at least I know it's not (or should not) a hardware problem.
Everything else works as expected, but the LAN91C96 driver does not enable the board network interface.
Environment: Hardware: Lubbock Board from Intel, wired to an IBM Laptop. U-boot version: 1.3.3 (tried with 1.3.1, 1.20, same results) mac address: tried with the one generated by the eth_gen_tool, and the original hardware one. Default 'lubbock.h' file, heavy edited one, etc... No luck.

^^ Hmmm, what base are we using here? Base 26? :-D
stdin=serial stdout=serial stderr=serial
Something odd I noticed:
$ tftpboot
Warning: MAC addresses don't match: HW MAC address: 01:00:01:00:01:00 "ethaddr" value: 00:02:B3:00:8F:xx Using MAC Address 00:02:B3:00:8F:xx
I'm assuming you didn't hand edit in the "xx" out of paranoia.
Linux detects the correct Mac Address without any configuration, why u-boot reads 01:00:01:00:01:00?
Beats me.
Any idea?
Try a valid MAC address?
Good luck, gvb
