svn commit: r196649 - head/sys/netinet6

Author: qingli

New Revision: 196649
URL: http://svn.freebsd.org/changeset/base/196649

Log:
  Prefix on-link verification is being performed on statically
  configured prefixes. Since these statically configured prefixes
  do not have any associated advertising routers, these prefixes
  are treated as unreachable and those prefix routes are deleted
  from the routing table. Therefore bypass prefixes that are not
  learned from router advertisements during prefix on-link check.
