You're exceeding me as a control freak, and that's saying something. The guy got the numbers for us, in response to their claim that on their systems cpu utilization is poor due to NAPI. Are you not convinced of this yet? Will a hundred new sets of numbers using the precise driver and protocol of your choosing convince you more of this? I think you're making unreasonable reqeusts of the problem submitter at this point, and we should be sending them patches to test not a new set of tests to run.
