Did anyone check to see if the Intel announcement had a 2 at 0x47f? :)

I do have a machine with these controllers that had a bridge "hang" in a
very odd fashion a while back, but it didn't repeat. It wasn't a
SuperMicro board, which is what some posters were saying were affected.

I would imagine a large ping packet (as used to test MTU) should
inoculate any affected interface if issued at boot, I don't think our
padding lines up with the problem. Once an interface sees a packet with
anything else at 0x47f, it's no longer affected, so there's a narrow
window of vulnerability in affected NICs.
