Right. So for additional context for folks less familiar with selftests the two minor inconveniences which made "supporting KTAP" a less exciting option are: (a) we run make run_tests which wraps things in an outer TAP, so we'd end up with a hybrid, anyway; (b) NIPA only supports one level of subtests. Thanks for the review!

The Python lib based tests report that they are producing "KTAP version 1", but really we aren't making use of any KTAP features, like subtests. Our output is plain TAP. Report TAP 13 instead of KTAP 1, this is what mptcp tests do, and what NIPA knows how to parse best. For HW testing we need precise subtest result tracking.
