Spooky http://en.wikipedia.org/wiki/Cisco_PIX Some Intel-based Ethernet cards for the PIX are identified at boot with the designation "mcwa". This designation denotes a multicast <http://en.wikipedia.org/wiki/IP_multicast>; receive bug <http://en.wikipedia.org/wiki/Software_bug>; in the card's firmware that the designers addressed with a feature they called *M*ulti *C*ast *W*ork *A*round. ...I've seen this happen with 1 fxp card I used to have, I don't know if this was a recycled PIX part or not. Think it was 82559ED off the top of my head.
