New Revision: 226239
URL: http://svn.freebsd.org/changeset/base/226239
Log:
MFC 225223
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.
