  Modified files:
    sys/netinet          ip_mroute.c 
  Log:
  If the rendezvous point for a group is not specified, do not send
  IGMPMSG_WHOLEPKT notifications to the userland PIM routing daemon,
  as an optimization to mitigate the effects of high multicast
  forwarding load.
  
  This is an experimental change, therefore it must be explicitly enabled by
  setting the sysctl/tunable net.inet.pim.squelch_wholepkt to a non-zero value.
  The tunable may be set from the loader or from within the kernel environment
  when loading ip_mroute.ko as a module.
