New Revision: 226040
URL: http://svn.freebsd.org/changeset/base/226040

Log:
  The IFA_RTSELF instead of the IFA_ROUTE flag should be checked to
  determine if a loopback route should be installed for an interface
  IPv6 address. Another condition is the address must not belong to a
  looopback interface.
