That test should be a negative test as is the first one in that group -
in both cases the address bind should fail since the socket is not in
the VRF but the address is. The first on currently shows "OK" but that
is because of 5cad8bce26e01 that made changes to the config to validate
MD5 changes. Will send a patch to fix.
