I'm using tri mode ethernet mac v5.5 in my design on custom board. I've adopted CoreGen's example project for my needs. I've connected my board with ethernet cable to PC and I have program which sends UDP frames and I want to see loopback frames in WireShark but I can't see any answer from board.
The question is:
Does loopback in pat_gen block provides loopback for UDP frames? With what type of frames does pat_gen works correctly?

Check if loopback is enabled or still in pattern generator mode.
In loopback mode if address swap is enabled then it swaps the destination and source MAC address and send the data on the TX and address swap is not enabled then the received data is looped to TX with out any changes.
The pattern generator send basic Ethernet frames(no udp or ip).

When there is address filters on the far end the Swap logic will swap the destination and source MAC addresses so that the packets are received by the far end.
