I know, hence my lobby :-)

Most importantly, they allow a Solaris machine to run a pruning
version of the multicast routing daemon without applying kernel
patches :-) (People who run non-pruning multicast routing daemons
should be taken out and shot, and rightly so.)
They also upgrade the host implementation to IGMPv3 from IGMPv2, but
that's not very interesting/useful.
They also correct some bugs in the shipping 2.5.1 multicast
code:
1. A race condition in the igmp module that causes panic in a mutithreaded
machine
2. The membership to INADDR_ANY was wrongly reports by a multicast router.
Functionally speaking, they replace the following:
/kernel/drv/ip
/kernel/drv/arp
/kernel/drv/icmp
/kernel/drv/udp
/kernel/drv/tcp
/usr/sbin/ifconfig
/usr/include/netinet/igmp.h
/usr/include/netinet/igmp_var.h
/usr/include/netinet/in.h
/usr/include/inet/ip.h
/usr/include/netinet/ip_mroute.h
/usr/include/sys/sockio.h
They include support for 103630-01 and 103582-01.
