These were missing as it wasn't clear, when the other tests were
introduced, if using the global address of a namespace, from the
host, should have resulted in traffic being routed via the tap
interface (as opposed to the loopback interface). We now clarified
that's actually the case.
Use same values and thresholds as the tests for loopback traffic, as
throughput figures currently indicate there isn't much difference.
