Also move the sampling into ether_input() where it can happen
at the interrupt and not within splnet() processing, which might
be less random. Discussed with mickey.
OK markus@, mcbride@

decent drivers prefer to have a lot of packets on the send queue so they
can queue a lot of them up on the tx ring and then post them all in one
big chunk. unfortunately our stack queues one packet onto the send queue
and then calls the start handler immediately.
this mitigates against that queue, send, queue, send behaviour by trying to
call the start routine only once per softnet. now its queue, queue, queue,
send.
this is the result of a lot of discussion with claudio@
tested by many.

all the original ones did, the recently added ones for labels per interface
didn't. no cookie for reyk ;(

before it is removed from the multicast group in_delmulti() will try to
access the no longer available ifp.
We invalidate the ifa_ifp back pointer in the ifa in if_detach() now and use
the ifa_ifp in in_delmulti() instead of the internal inm_ifp. By doing it
this way we know if the interface was removed.
This fixes a kernel panic triggered by ospfd and gif(4) tunnels.
looks good henning@ reyk@

which will be used for new interface routes. For example,
ifconfig em0 10.1.1.0 255.255.255.0 rtlabel RING_1
will set the new interface address and attach the route label RING_1 to
the corresponding route.

packet. If multiple packets come in on a single interrupt the times mixed into
the randomness pool will be identical or predictably close anyways, and
nanotime() is expensive.

This reduces group failover time to a few milliseconds.

This provides a similar functionality as ARP balancing,
but also works for traffic that comes across routers.
IPv6 is supported as well.
The configuration scheme will change as soon we have sth better.
Also add support for changing the MAC address on carp(4)
interfaces. (code from mcbride)

by Andrew Thompson (thompsa@freebsd.org). The local changes include
adoption to our bridge code, reduced stack usage and many other bits.
If stp is enabled, RSTP will now be used by default.
Thanks for help from Andrew.

as the resulting demotion counter value is in range. previously, we only
allowed +/- 1. ok mpf mcbride deraadt

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.

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.

but go through a provided wrapper.
also provide rt_lookup() instead of doing the lookup manually in many places.

when the interface is deleted to a function in route.c, and replace
the copies of that code by calls to that function
from basel almost-hackathon

to trigger an if_group_egress_build() call, stop looking at the mask in the
v4 case, at least until I figured out why we sometimes see masks full of
crap.

handles IPv4 and IPv6 as well as multipath routes.
follows default route changes, of course.
eases writing pf rulesets especially on laptops etc. that use different
interfaces depending on the environment (wired, wireless, ...)
