ca4125f7b3 Create a subtree 'harp' of the net sysctl tree. This uses a fixed
OID as the other protocol family sub-trees do, that is equal to the
protocol family identifier. Make the ATM layer debugging flags
available under this tree.

b92ba02261 Remove the zone limits for all the zones used in the ATM code.
These were a left over from when the private memory pools were
converted to use uma zones. The limit of UMA zones, however,
works differently. When a zone is limited to only one or two pages
than, on multi-cpu systems, processes can get stuck on the zonelimit,
because all remaining free items are in caches of other CPUs.

Also add rudimentary error handling in some places (panic) when a zone
cannot be created.

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.

672cc99ed3 - Change the ATM stack functions to use intptr_t instead of int for opaque
arguments.
- Fix a few other places that assumed that sizeof(int) == sizeof(void *).

fe1c49fbba - Chainsaw the storage pool code. This was being used by a bunch of code
within the HARP atm stack and the hea and hfa device drivers, but since
  all of these systems were changed to use UMA zones, there is no use for
  the api any longer.

2647924585 - Replaced the Atm_connection storage pool with an uma_zone of
Atm_connection items.
- Replaced the Atm_connvc storage pool with an uma_zone of Atm_connvc
  items.
- Created void atm_cm_init(void *) and added it to the netatm init code.
  I'm thinking that there will definetly be more ``subsystem'' init
  functions to be added so I'll probably change these calls to be a for
  loop through init routines (or something).

6008862bc2 Change callers of mtx_init() to pass in an appropriate lock type name. In
most cases NULL is passed, but in some cases such as network driver locks
(which use the MTX_NETWORK_LOCK macro) and UMA zone locks, a name is used.

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.

6cb2a0952f Do some cleanups of the HARP atm codes interface into the system:
Define the NETISR just like all the other NETISRs.

unifdef -Usun -D__FreeBSD__  we will probably never support sun4c
and if we do we can't use the solaris code anyway and  I doubt
anybody will be running Fore ATM cards in then in the first place.
