f9d801d6f7 Include <sys/malloc.h> for the declaration of malloc(), etc. instead
of depending on namespace pollution 2 layers deep in <vm/uma.h>.  Fixed
most nearby include messes (another like this, several the opposite of
this, and some formatting).

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

dd937e32bd Make the ioctl() interface cleaner with regard to types: use size_t
instead of int where the variable has to hold buffer lengths,
use u_int for things like number of network interfaces which
in principle can never be negative.

06055f52f3 Convert a lot of uma_zalloc() calls to be NOWAIT instead of WAITOK. All
these may be called from contexts where we cannot sleep (callout handlers
for example).

05ab0ba3b5 Allocate network interfaces from malloc() instead of using a zone.
Usually one needs only a couple of them so using a zone is waste
of memory (esp. on multi-cpu systems).

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.

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.

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.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.
