To minimise path disruptions, this implements recommendations made in RFC2992 -
the hash-threshold mechanism to select paths based on source/destination IP
address pairs, and inserts multipath routes in the middle of the route table.
To enable multipath distribution, use:
sysctl net.inet.ip.multipath=1
and/or:
sysctl net.inet6.ip6.multipath=1

here, make sure they compile with or without IPSEC, you morons!

As a first user, move the global carp(4) demotion counter
into the interface group. Thus we have the possibility
to define which carp interfaces are demoted together.
Put the demotion counter into the reserved field of the carp header.
With this, we can have carp act smarter if multiple errors occur.
It now always takes over other carp peers, that are advertising
with a higher demote count. As a side effect, we can also have
group failovers without the need of running in preempt mode.
The protocol change does not break compability with older
implementations.

Additionally add the IP_RECVIF option which returns the interface a packet

need to save/restore it.
- inp->inp_laddr should be set _before_ calling pcb_disconnect().
otherwise pcb_disconnect() calls pcb_rehash() with the old laddr.
[ currently this is not a problem since the hash ignores laddr ]

code breaks multicast on gif(4) interfaces and it is far better to configure
a real gif(4) tunnel instead of a multicast tunnel as the latter is almost
not manageable. OK norby@, mblamer@

directly. rather provide a rt_lookup function for regular lookups,
and a rt_gettable for those that need access to the head for some reason.
the latter cases should be revisted later probably so that nothing outside
the routing core code accesses the heads at all...

router so back out the routing stuff to pre-eurobsdcon where my machine
doesn't crash immediately.
i am happy to test diffs and report success/failures but i am not happy
to have instantaneous crashes when i reboot with a new kernel that was
compiled from pristine sources.
if you are going to be an elitist asshole then you could at least make
sure your code works.

also provide rt_lookup() instead of doing the lookup manually in many places.
