* Routes that belong to an interface without a link are no longer

ignored, but other routes will be preferred if available.
* This fixes problems with networking cards that don't report their
  link status correctly (ipro100, see bug #1936), or too late 
  (nforce, ipro1000, see bug #1941). Drivers that did not report any
  status at all were not affected, though.
