  SVN rev 201284 on 2009-12-30 21:51:23Z by qingli
  
  Multiple IPv6 addresses of the same prefix can be installed on the
  same interface. The first address will install the prefix route into
  the kernel routing table and that prefix will be marked as on-link.
  Without RADIX_MPATH enabled, the other address aliases of the same
  prefix will update the prefix reference count but no other routes
  will be installed. Consequently the prefixes associated with these
  addresses would not be marked as on-link. As such, incoming packets
  destined to these address aliases will fail the ND6 on-link check
  on input. This patch fixes the above problem by searching the kernel
  routing table and try to find an on-link prefix on the given interface.
