* First you should examine how far your sent/received packets get.
  Determine if the core gets any packet ->
  Are the BDs changing, if yes what is in the buffer.
* Disable caches
* Is the MAC address set properly (Endianess)
  try with promiscious mode.
* Use tcpdump (or similar) to log the traffic.
* Turn on ethernet debugging in RedBoot (fconfig)

Try to isolate the problem.

good luck, christoph
