entering rtentry's for hosts we're not actually communicating
with.
Do this by invoking the ctlinput for the protocol, which is
responsible for validating the ICMP message:
* TCP -- Lookup the connection based on the address/port
pairs in the ICMP message.
* AH/ESP -- Lookup the SA based on the SPI in the ICMP message.
If validation succeeds, ctlinput is responsible for calling
icmp_mtudisc(). icmp_mtudisc() then invokes callbacks registered
by protocols (such as TCP) which want to take some sort of special
action when a path's MTU changes. For TCP, this is where we now
refresh cached routes and re-enter slow-start.
As a side-effect, this fixes the problem where TCP would not be
notified when a path's MTU changed if AH/ESP were being used.
XXX Note, this is only a fix for the IPv4 case. For the IPv6
XXX case, we need to wait for the KAME folks.

Implement SCBUSACCEL ioctl.
Snapshot of work in progress on tagged queuing: we can send/receive
queue tag messages. Infrastructure to manage multiple commands per
devices not here yet.
setgroups() did not result in actual changes. This has the nice
side effect that we don't needlesly allocate new credential and
resource limit data structures.
This is so that non setuid programs that call seteuid(getuid()),
don't end up setting P_SUGID, resulting in broken behavior [i.e.
non setuid ssh, doesn't read ~/.hostaliases...].
This is a good candidate for a pullup, if someone reviews it.
Drochner's work made in nisimura-pmax-wscons branch. Still a little
to do before useful for DECstation. MI softintr required.
- allow wildcard matchs to have zstty/zskbd/zsms in default hardware
configuration.
- abandon to check zs_ioasic_cnattach() return value; it doesn't fail.
- have zs_ioasic_cnattach() serial line parameters hardcoded inside, in
symmetry with zs_ioasic_lk201_cnattach().
ip_output(). This flag, if set, causes ip_output() to set
DF in the IP header if the MTU in the route is not locked.
This allows a bunch of redundant code, which I was never
really all that happy about adding in the first place, to
be eliminated.
Inspired by a similar change made by provos@openbsd.org when
he integrated NetBSD's Path MTU Discovery code into OpenBSD.

Also fix egregious bug where we would never decrement
the islocked recursion counter. I guess this means
that we don't recurse on this platform! All of this should
go away when we have real lock primitives to use in drivers.

as I get that running for myself.
