Hi Michael !

It's the dual controller of an Apple Quad G5, thus afaik in an HT2000
chip:

0001:05:04.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5780 Gigabit Ethernet (rev 03)

And the dmesg bits:

tg3.c:v3.65 (August 07, 2006)

As for the tcpdump output, well, I have a 3Gb file for now :) I need to do a bit of surgery on it to
get only the interesting part. I'll try to do that later today (but it may have to wait for monday).

Cheers,
Ben.
