You could build with DEBUG=netdevice:3. That will show you a message for every transmit, transmit completion, and receive: you should be able to figure out from this which parts (if any) of the datapath are still working. For example, you may see receives (from broadcast traffic on the network) even if iPXE is failing to transmit anything.

If you use DEBUG=netdevice:3,intel:3 then you will also see the status of the transmit and receive head/tail pointers as read back from the hardware. This may also give some clue as to the problem.
