Good point. But I think it is unlikely. Currently, it generates single fat flow
and if someone uses it for testing, then Rx side likely uses single core. Even
if it gets to generate multiple flows, it would be same to such a case.

However, it is my speculation. If you disagree anyway, I'll stash it for 18.05
and add a new knob to enable it. I'm okay with that because it is just for
convenience, not an urgent issue.

Thanks,
