* 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
