So maybe in the end, we can try to have something a bit less python-y, while still
using extensive documentation using sphynx doc format ?

Let me send a V2 with the full test list, we'll see how much scaffolding
we can build for ethtool testing, and how. I suspect that running/skipping based on
the device's capabilities is going to be used throughout lots of tests
beyond pause.

For now the important part is to get that test list right, and iterate on the
test implementation once we agree on what to test, why and how.
