OpenCores MAC driver error mesages

Documentation ... yes that would be nice. Unfortunately all that exists is what is found in the accompanying Word document which is pretty minimal.

Obvious things to check:

1 - Have you constrained the timing for the PHY?

2 - Are you meeting timing requirements on all clock domains?

3 - Can you view the packets on the network (via Wireshark or some other packet sniffer)?

4 - What speed and duplex are you running in?

5 - What version of the MAC are you using?

6 - What version of the tools are you using?

BTW - You should be able to bump the TX fifo back down. The larger fifo really won't help much.
