I feel that those are much better names. Should I rename also the make

Sure, I can do that.

I can add that

I've thought about it, but I'm not sure how easy it would be in practice
to support other OS (especially for namespaces).
I can move some more linux specific code into the macros
(like the ip netns exec commands), but my goal for now would be to be
able to test the userspace datapath as well as the kernel module.

That's better, I'll add the ON_EXIT.
Thanks for taking a look at this and for all your suggestions!
I'll post a v2 soon
