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.

93cded6e45 Devices that are running at splimp MUST use ng_queue_data() 
instead of ng_send_data().
The latter could lead to running the IP stack at splimp
instead of splnet, (among other problems) (that MAY be safe
but I wouldn't count on it).

Noticed while preparing a new set of netgraph stuff.

599fcb028d Driver for DEC "Tulip" based WAN cards from LanMedia Corporation. 
This driver should support both the SSI (V.35 etc) E1/T1 unchannelized,
DS3 and HSSI cards.  Only tested on the SSI card.

More info at: http://www.lanmedia.com

Thanks to LanMedia for donating two LMC1000P cards.
