b36ea4aac2 Fix a (mostly harmless) scheduling-in-the-past problem with
dummynet (already fixed in -stable, was waiting for Jordan's
approval due to the code freeze).

6ef0117870 Sorry in this just befor code freeze commit.
This is fix to usr.sbin/trpt and tcp_debug.[ch]
I think of putting this after 4.0 but,,,

 -There was bug that when INET6 is defined,
  IPv4 socket is not traced by trpt.

 -I received request from a person who distribute a program
  which use tcp_debug interface and print performance statistics,
  that
    -leave comptibility with old program as much as possible
    -use same interface with other OSes

  So, I talked with itojun, and synced API with netbsd IPv6 extension.

makeworld check, kernel build check(includes GENERIC) is done.

But if there happen to any problem, please let me know and
I soon backout this change.

9d11326d86 Mitigate the stream.c attacks
o Drop all broadcast and multicast source addresses in tcp_input.
o Enable ICMP_BANDLIM in GENERIC.
o Change default to 200/s from 100/s.  This will still stop the attack, but
  is conservative enough to do this close to code freeze.

This is not the optimal patch for the problem, but is likely the least
intrusive patch that can be made for this.

26fcba4c5a Move the *intrq variables into net/intrq.c and unconditionally
include this in all kernels.  Declare some const *intrq_present
variables that can be checked by a module prior to using *intrq
to queue data.

Make the if_tun module capable of processing atm, ip, ip6, ipx,
natm and netatalk packets when TUNSIFHEAD is ioctl()d on.

This must be one of the reason why connections over IPsec hangs for

But there still seems to be another bug and the problem is not yet fixed.

554cd7f404 Implement per-flow queueing. Using a single pipe config rule,
now you can dynamically create rate-limited queues for different
flows using masks on dst/src IP, port and protocols.
Read the ipfw(8) manpage for details and examples.

Restructure the internals of the traffic shaper to use heaps,
so that it manages efficiently large number of queues.

Fix a bug which was present in the previous versions which could
cause, under certain unfrequent conditions, to send out very large
bursts of traffic.

All in all, this new code is much cleaner than the previous one and
should also perform better.

the old one: an unnecessary define (KLD_MODULE) has been deleted and
the initialisation of the module is  done after domaininit was called
to be sure inet is running.

Some slight changed were made to ip_auth.c and ip_state.c in order
to assure including of sys/systm.h in case we make a kld

Make sure ip_fil does nmot include osreldate in kernel mode
