Intel 810 NIC hashing issue #634
Description
I'm currently working on a proof of concept for a 100G capable Gatekeeper instance. It has a quartet of these Intel 810 based NICs installed. I've managed to work through a number of hangups, most notably with the ddp firmware, but seem to be getting stuck on this particular hashing related issue. See copypasta from the logs. Let me know if you need more info.
