567ba9b00a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

2126402238 Apply error and success logic consistently to the function netisr_queue() and
its users.

netisr_queue() now returns (0) on success and ERRNO on failure.  At the
moment ENXIO (netisr queue not functional) and ENOBUFS (netisr queue full)
are supported.

Previously it would return (1) on success but the return value of IF_HANDOFF()
was interpreted wrongly and (0) was actually returned on success.  Due to this
schednetisr() was never called to kick the scheduling of the isr.  However this
was masked by other normal packets coming through netisr_dispatch() causing the
dequeueing of waiting packets.

f85a384d67 Implement a traffic shaping option for the PCA200 for CBR channels.
This is controlled by a per-adapter sysctl hw.atm.hfaX.shape. When
set to 0, no shaping occures. When set to 1 at most 1 channel is
shaped. When set to 2 all CBR channels are shaped. Note, that the
latter may actually not work, because of the adapter supporting
the shaping of only one PDU at the same time.

4bd81e8df0 Make the driver to work with firmware version 4.1.12 (other 4.X.Y should
also do it). Three problems have been encountered:

1. The initialisation command does not work in interrupt mode. Whether
   this is a firmware bug or a feature is not clear. The original Fore
   drivers execute the initialize command always in polling mode, so
   it appears that this behaviour is expected. When we detect a 4.X.Y
   firmware do busy wait on the command status.

2. The command code of the GET_PROM command has changed. This is an
   unofficial command anyway. What was GET_PROM in 3.X.Y is CLEAR_STATS
   in 4.X.Y (although unimplemented in the firmware). We need to
   use the correct code depending on the firmware.

3. The 4.X.Y firmware can set the error flag in the command status
   without also setting the completion flag (as the documenation says).
   Check both variants.

An additional field in the per-card structure fu_ft4 is TRUE when we have
detected a 4.X.Y firmware. Otherwise it is false. The behaviour of the
driver when using a 3.X.Y firmware should be identical to the previous
behaviour.

This change will enable traffic shaping of (at least one) CBR channels.

04e28d5a81 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.

o eliminate the most heavily used aux mbufs by adding an additional struct

954e1d2ccd 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.
