Interesting debugging: Specific packets cause some Intel gigabit ethernet controllers to reset

[EWieling at nyigc.com (Eric Wieling)]

I have come to believe the Intel 82574L is the worst Ethernet chip in the universe.    We had horrible issues with it (random bursts of dropped packets showing in ifconfig).  We ended up simply putting a card based on a different chip into our systems and all our issues went away.
