The tests under tools/testing/selftests/net/forwarding/ aren't executed as part of the Makefile. The config file is there mainly so that people will know which config options they need in order to run the tests. The tests can be added to the Makefile, but some of them take a few minutes to complete which is probably against "Don't take too long;" mentioned in Documentation/dev-tools/kselftest.rst.
