This should be interesting to people on this list. Please test Bruce's=20
changes and report back. I believe it should be possible/trival to=20
provide a patch for RELENG_6, but I don't have time right now. I will=20
provide one tomorrow - unless Bruce is quicker. I believe people seeing=20
this trouble with CARP and/or pfsync are on this list.

Modified files:
sys/net if.c if_var.h
sys/netgraph ng_ether.c
sys/netinet in.c in_var.h
sys/netinet6 mld6.c
Log:
Implement reference counting for ifmultiaddr, in_multi, and in6_multi
structures. Detect when ifnet instances are detached from the network
stack and perform appropriate cleanup to prevent memory leaks.
This has been implemented in such a way as to be backwards ABI
compatible. Kernel consumers are changed to use if_delmulti_ifma();
in_delmulti() is unable to detect interface removal by design, as it
performs searches on structures which are removed with the interface.
With this architectural change, the panics FreeBSD users have
experienced with carp and pfsync should be resolved.
