765b90447e These diffs modify the behaviour of multicast clients to conform with the
IGMPv2 spec.  This fixes the following bugs:

o ntohs() on a char provides silly results
o timer needs to be scaled to units of PR_FASTHZ; this was being done
  inconsistenly so now it gets done when it is initialized.

6b067b0744 #ifdef'd my Nagel/ACK hack with "TCP_ACK_HACK", disabled by default. I'm
currently considering reducing the TCP fasttimo to 100ms to help improve
things, but this would be done as a seperate step at some point in the
future.
This was done because it was causing some sometimes serious performance
problems with T/TCP.

748e0b0acc Make networking domains drop-ins, through the magic of GNU ld. (Some day,
there may even be LKMs.)  Also, change the internal name of `unixdomain'
to `localdomain' since AF_LOCAL is now the preferred name of this family.
Declare netisr correctly and in the right place.

0d7b7d3ea7 Changed in_pcblookuphash() to not automatically call in_pcblookup() if
the lookup fails. Updated callers to deal with this. Call in_pcblookuphash
instead of in_pcblookup() in in_pcbconnect; this improves performance of
UDP output by about 17% in the standard case.

755c1f07c8 Fix a bug in tcp_input reported by Rick Jones <raj@hpisrdq.cup.hp.com>.
If a goto findpcb occurred during the processing of a segment, the TCP and
IP headers were dropped twice from the mbuf which resulted in data acked
by TCP but not delivered to the user.

ffa5b11ab5 in_var.h: in_multi structures now form a queue(3)-style LIST structure
in.c: when an interface address is deleted, keep its multicast membership
.     records (attached to a struct multi_kludge) for attachment to the
.     next address on the same interface.  Also, in_multi structures now
.     gain a reference to the ifaddr so that they won't point off into
.     freed memory if an interface goes away and doesn't come back before
.     the last socket reference drops.  This is analogous to how it is
.     done for routes, and seems to make the most sense.

20e8807c09 This should be splimp() rather than splnet() since ifaddrs might go away

9b626c29f7 Fix race conditions involved in setting IP multicast options. This should
fix Dennis Fortin's problem for good, if I've got it figured out right.

(The problem was that a `struct ifaddr' could get deleted out from under
the current requester, thus leaving him with an invalid interface pointer
and causing even more bogus accesses.)

d99c7a23fa This set of patches enables IP multicasting to work under FreeBSD. I am
submitting them as context diffs for the following files:

sys/netinet/ip_mroute.c
sys/netinet/ip_var.h
sys/netinet/raw_ip.c
usr.sbin/mrouted/igmp.c
usr.sbin/mrouted/prune.c

The routine rip_ip_input in raw_ip.c is suggested by Mark Tinguely
(tinguely@plains.nodak.edu). I have been running mrouted with these patches
for over a week and nothing has seemed seriously wrong. It is being run in
two places on our network as a tunnel on one and a subnet querier on the
other. The only problem I have run into is that mrouted on the tunnel must
start up last or the pruning isn't done correctly and multicast packets
flood your subnets.
