Ahh, Scott shed some light.
Perhaps this is what John wants to find on the CD:

There's another one here (but not on the CD URL):

I think you're more after a SAP field at that point from what I'm
remembering... DSAP of 0x42 should indicate a BPDU. I think the SSAP is
the same within the LLC header.
If you have a switch and Ethereal/Wireshark sniffer lying around, you can
verify this.

Thanks Sean. IP, IPv6, ARP are all there.
I am still looking for BPDU's Ethertype.
