the remainder of the network stack from splimp to splnet.

bpf FILDROP interface exists for about one year but the required
interface to the drivers was missing - so it was useless. this new
approach based on a design by henning@ uses a new mbuf flag to mark
filtered packets and to drop them in the generic network stack input
routines (like ether_input).
for example; after some additional testing, this could be used by
dhclient to filter everything except DHCP packets (track tech@
for a corresponding dhclient diff). the "filter dropped" packets won't
reach the network stack. so it's probably some kind of a very basic
application layer packet filter ;).

in the data part for the data from the previously distinct tags.
look up the tag early and carry a pointer to it around.
makes the code easier and saves some tag lookups and thus helps performance,
as proven by tests run by Schberle Dniel <Schoeberle.Daniel@aamtech.hu>
Initially hacked up somewhere over the atlantic ocean in an A330

consume vlan frames that no vlan interface wants, so they can
still be bridged.
This way, the bridge can bridge encapsulated frames _and_ bridge
between vlan interfaces.

Advertisements run through the carp interface first.
So we just take the address from ifp0.
While we're there,
also remove carp_macmatch6, which isn't used anymore.

style as vlan(4). carp interfaces no longer require the physical interface
to be on the same subnet as the carp interface, or even that the physical
interface has an adress at all, so CARP can now be used on /30 networks.

Also, while we're here, make the loop counter size_t.

things such that code that only need a second-resolution uptime or wall
time, and used to get that from time.tv_secs or mono_time.tv_secs now get
this from separate time_t globals time_second and time_uptime.

is full, along with a timer that unsets it again after 10ms.
The input queue beeing full is a reliable indicator for CPU overload, and
this flag allows other subsystems to cope with the situation.

replace arc4random() with the more mundae random()&0xff as the use
of a strong PRNG is not need here, where this code just helps fix
up broken MAC addresses anyway

the new model removes direct references to the fields in ifp->if_snd,
and defines the following macros to manipulate ifp->if_snd.
IFQ_ENQUEUE(ifq, m, pktattr, err)
IFQ_DEQUEUE(ifq, m)
IFQ_POLL(ifq, m)
IFQ_PURGE(ifq)
IFQ_IS_EMPTY(ifq)
the new model also enforces some rules regarding how to use these macros.
details are descrined in
