0f810ef0a2 Merge amd64 and i386 bus.h and move the resulting header to x86. Replace
the original amd64 and i386 headers with stubs.

Rename (AMD64|I386)_BUS_SPACE_* to X86_BUS_SPACE_* everywhere.

4ba3c79b59 This driver has two modes, a netgraph mode and an ifnet mode. In the
netgraph mode it used a private timer to drive the transmit watchdog.  In
the ifnet mode it used if_watchdog.  Now it always uses the private timer.

b523608331 When user_frac in the polling subsystem is low it is going to busy the
CPU for too long period than necessary.  Additively, interfaces are kept
polled (in the tick) even if no more packets are available.
In order to avoid such situations a new generic mechanism can be
implemented in proactive way, keeping track of the time spent on any
packet and fragmenting the time for any tick, stopping the processing
as soon as possible.

In order to implement such mechanism, the polling handler needs to
change, returning the number of packets processed.
While the intended logic is not part of this patch, the polling KPI is
broken by this commit, adding an int return value and the new flag
IFCAP_POLLING_NOCOUNT (which will signal that the return value is
meaningless for the installed handler and checking should be skipped).

Bump __FreeBSD_version in order to signal such situation.

eb53283166 Rename several functions in if_lmc with potential name collisions with
global symbols, such as raw_input and raw_output, to have lmc_ prefixes.
This doesn't affect actual functionality since the functions are static,

d39a762fb7 Reintroduce the lmc T1/E1/T3 WAN driver. This version is locked, supports
interface polling, compiles on 64-bit platforms, and compiles on NetBSD,
OpenBSD, BSD/OS, and Linux.  Woo!  Thanks to David Boggs for providing this
driver.

Altq, sppp, netgraph, and bpf are required for this driver to operate.
Userland tools and man pages will be committed next.

73d768d3da Continue to remove drivers that don't compile and haven't compiled in
a long time: lmc The LAN Media Corp PCI WAN driver based on tulip.
This driver hasn't compiled for 3 years since the PCI compat shims
were removed, and Lan Media appears to have gone out of business.
These cards appear to be rare (a recent search of ebay had no hits).

Should someone wish to revive this driver, submitting patches to make
it compile plus a testing report will bring it back.

d9b10e2248 lmc_ifup() was not checking the state of the interface. This would
cause the watchdog to (incorrectly) detect the interface state
going from down to up one second after lmc_ifup() was called,
causing lmc_ifup() to be called again, and resetting everything.
Fix by checking the interface state within lmc_ifup().

0c949560a1 Divorce the kernel binary ABI version number from the message

Also fix modules that don;t handle the fact that a caller may not supply
a return message pointer. (benign at the moment because the calling code
checks, but that will change)

This clears out my outstanding netgraph changes.
There is a netgraph change of design in the offing and this is to some
extent a superset of soem of the new functionality and some of the old
functionality that may be removed.

This code works as before, but allows some new features that I want to
work with and evaluate. It is the basis for a version of netgraph
with integral locking for SMP use.

This is running on my test machine with no new problems :-)

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.

283b0e73a4 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.
