I did not know about run_kselftest.sh. From a quick look, it seems to
require selftests to be installed to run them. I think nipa relies on
something slightly different, it does something like this, AFAIU this
runs an individual kselftest without requiring it to be installed
first (which is nice):

make -C tools/testing/selftests TARGETS="net"
TEST_PROGS="rxtimestamp.sh" TEST_GEN_PROGS="" run_tests

It may be worth it to check if these added tests can be ran in a similar way.

They should, the ksft infra converges into the same bash script
(runner.sh) whether we enter via make or via the "installed" runner.

This may also solve your issue with 'intermediate output' being
printed after every test. AFAIU if the tests can be ran individually
using a command like this, then you don't need intermediate output,
maybe.

selftest infra tries to prefix raw output with # to make sure that
random prints don't get mixed with KTAP. IIRC there are two ways
to do that, one is a perl script and that doesn't buffer, but if
there's no perl in PATH it runs the output thru sed, and sed buffers.
