Hi Federico
Sorry for not replying to this sooner, I just fished it out of my pile
of unprocessed email while I was winding things down for the holidays...

I'd be happy to consider your tool for inclusion into xdp-tools, or into
a separate repository under the xdp-project github organisation if that
fits better. I think that will mostly depend on how much surrounding
setup code is needed to run the experiments: the utilities in xdp-tools
are mostly fairly lightweight standalone binaries, so if something more
is needed a separate repository may be better.
As for how to structure the test utility, that's hard to say off-hand.
But one important consideration is making it easy to run (so as few
assumptions on the environment as possible), and easy to automate (so
that we ideally can use it as an automated CI-style test for performance
regressions).
Hope that helps! :)
