 AIUI downing the interface should remove its link-level route. If this
 is not happening, it should be easy to confirm, and it should be
 possible to work around the problem by nuking the route explicitly in
 that script.
 
 As to why it might not be happening... probably someone who knows more
 about the network code needs to investigate.
