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.
