[PATCH net-next v2 1/2] selftests: drv-net: devmem: fix 5-tuple flow steering

When configuring traffic for the devmem tests, 5-tuple flow steering may
be required if the environment does not provide network namespaces.
Pass the correct remote address parameter and fall back to 5-tuple flow
steering if netns is not available.
