I'm sorry, David as been working in netdev for a long time. I have a tendency to address the person I'm replying to, assuming their level of understanding of the problem space.

I just meant forwarding offload _which I said_. You didn't understand and now you're accusing me of "making stuff up". This whole conversation is such a damn waste of time.
