9188b4a169 Introduce ip_fastforward and remove ip_flow.
Short description of ip_fastforward:

 o adds full direct process-to-completion IPv4 forwarding code
 o handles ip fragmentation incl. hw support (ip_flow did not)
 o sends icmp needfrag to source if DF is set (ip_flow did not)
 o supports ipfw and ipfilter (ip_flow did not)
 o supports divert, ipfw fwd and ipfilter nat (ip_flow did not)
 o returns anything it can't handle back to normal ip_input

Enable with sysctl -w net.inet.ip.fastforwarding=1

1cafed3941 Update netisr handling; Each SWI now registers its queue, and all queue
drain routines are done by swi_net, which allows for better queue control
at some future point.  Packets may also be directly dispatched to a netisr
instead of queued, this may be of interest at some installations, but
currently defaults to off.

4141b621ac When a packet is sent via a FDDI interface, perform appropriate MAC
transmission checks; when it is received, label the packet appropriately.
Although we don't have a local FDDI setup to test this with, the
labeling and checks are identical to other interface classes.

ifnet_addrs[i - 1]  -> ifaddr_byindex(i)

2a0c503e7a * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.
This is because calls with M_WAIT (now M_TRYWAIT) may not wait
  forever when nothing is available for allocation, and may end up
  returning NULL. Hopefully we now communicate more of the right thing
  to developers and make it very clear that it's necessary to check whether
  calls with M_(TRY)WAIT also resulted in a failed allocation.
  M_TRYWAIT basically means "try harder, block if necessary, but don't
  necessarily wait forever." The time spent blocking is tunable with
  the kern.ipc.mbuf_wait sysctl.
  M_WAIT is now deprecated but still defined for the next little while.

* Fix a typo in a comment in mbuf.h

* Fix some code that was actually passing the mbuf subsystem's M_WAIT to
  malloc(). Made it pass M_WAITOK instead. If we were ever to redefine the
  value of the M_WAIT flag, this could have became a big problem.

df5e198723 Lock down the network interface queues. The queue mutex must be obtained
before adding/removing packets from the queue.  Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.

IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue.  An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.

Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.
