Exactly, this are the top questions. I performed lots of tests on
hardware with which I'm working on and had a pretty good boosts
(I didn't mainlined my drivers yet unfortunately).
But this does not mean that GRO would be that nice for all kind of
devices *at all*. That's why I would like to see more test results
on different systems.
