Well this hurts. I have a critical machine with a dual NIC Intel motherboard. I had to abandon the 82579LM port because of unresolved bugs in the Linux drivers, and the other one is a 82574L, the one documented in this post. I suppose I can send just the right ICMP echo packet to router to make it send me back an innoculating frame.
