It is a good target but it is indeed a good idea to preserve the ability to run it outside of test_progs framework. Maybe we can eventually run it with the real hw (in loopback mode) from tools/testing/selftests/rivers/net/hw. And I don't think anybody is working on integrating it into test_progs. But Magnus/Maciej should have more context...
