Working on the 10GbE issue now. It's not playing nice, the firmware is seeing packets but replies from the firmware aren't going anywhere. Wireshark isn't seeing anything which probably means the problem is lower level than that (corrupted frames with bad CRC).

Time to fire up my trusty layer 1 packet sniffer.
