Thanks Brian!

I'll double check but I have tested in the past to make sure bonding
is multiplying my traffic B/W. I am using bonding in the Adaptive Load
Balancing (ALB) mode. I forget what tool I had used but I believe it
was indeed netperf.  Of course the advantage only comes when talking
to two+ peers at the same time.
