Each MPTCP subtest tests test__start_subtest(suffix), then invokes test_suffix(). It makes sense to add a new macro RUN_MPTCP_TEST to simpolify the code.

Please no. Don't hide it behind macros.
I understand, I'm personally not a big fan of hiding code being a macro too. This one saves only one line. Geliang added a few more tests in our tree [1], for a total of 9, so that's only saving 9 lines.
Related to that, if you don't mind, Geliang also added another macro -- MPTCP_SCHED_TEST -- for tests that are currently only in our tree [2] (not ready yet). We asked him to reduce the size of this macro to the minimum. We accepted it because it removed quite a lot of similar code with very small differences [3]. Do you think we should revert this modification too?
