Yeah, seems like the original document is here
http://www.kernel.org/pub/linux/kernel/people/marcelo/linux-2.4/Documentation/networking/bonding.txt

It was reading that document that made me want to ask more about this.
 Especially section 7:

"7.  Which switches/systems does it work with?

        In round-robin mode, it works with systems that support trunking:"

I'll give it a shot :->

So that's transmit, but I guess I wonder what about receiving traffic?
Aren't we really relying on the switch to do the right thing?

Anyway, thanks very much for taking the time to help me through this.

Cheers,
