 New Revision: 225223
 URL: http://svn.freebsd.org/changeset/base/225223
 
 Log:
   When an interface address route is removed from the system, another
   route with the same prefix is searched for as a replacement. The
   current code did not bypass routes that have non-operational
   interfaces. This patch fixes that bug and will find a replacement
   route with an active interface.
