[AusNOG] NIC Packets of death

[Heinz N]

Seems that certain packets can completely bring down certain Intel chipset 
network controllers.

>From the article:

"When I say "bring down" an ethernet controller I mean BRING DOWN an 
ethernet controller. The system and ethernet interfaces would appear fine 
and then after a random amount of traffic the interface would report a 
hardware error (lost communication with PHY) and lose link. Literally the 
link lights on the switch and interface would go out. It was dead. Nothing 
but a power cycle would bring it back. ."

Nasty, especially if the equipment is remote.

(Remains me of a remote exploit for Broadcom chipset a while ago).
