That would probably need to be a secondary process, hooking up to the testpmd process used for testing. Not the simplest solution.

If testpmd is the primary tool used for testing PMDs, it should support all features being tested. In other words: Testpmd needs to be updated, so it also shows speed_capa.

I also considered ethtool, but it is only listed under Other Example Applications, and has no maintainers. So that does not seem to have a promising future.
