The test does not follow the usual convention of forwarding tests that are expected to be run with both veth pairs and loop backed physical devices. See: tools/testing/selftests/net/forwarding/README (and existing tests for reference) This approach allows us to test both the software and hardware data paths. You can construct a test where you have multiple VRFs instead of multiple namespaces. These VRFs emulate your hosts and routers. Send multiple flows from one host and check the distribution across the multiple paths connecting your two routers. Change the seed, expect a different distribution. Go back to original seed and expect the original distribution.
