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.

unload method. Lots of old cruft is removed.

Thanks to WPaul for large clue-injection and debugging services.

21b8ebd926 Make all Ethernet drivers attach using ether_ifattach() and detach using
ether_ifdetach().

The former consolidates the operations of if_attach(), ng_ether_attach(),
and bpfattach(). The latter consolidates the corresponding detach operations.

2e2de7f23f Move code to handle BPF and bridging for incoming Ethernet packets out
of the individual drivers and into the common routine ether_input().
Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.

The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.

The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.

3e48370f70 Bounce a copy of the mbuf to the bpf listener when we submit the frames
for transmit to the adapter, not when we receive a transmit interrupt
indicating that they were sent.  This fix now allows tcpdump to produce
sane results by recording the timestamp at the point where the mbuf was
actually transmitted.

46783fb897 Remove NBPF conditionality of bpf calls in most of our network drivers.
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.

fcb893a801 Implement a new generic mechanism for attaching handler functions to
events, in order to pave the way for removing a number of the ad-hoc
implementations currently in use.

Retire the at_shutdown family of functions and replace them with
new event handler lists.

Rework kern_shutdown.c to take greater advantage of the use of event
handlers.

e9fc0b372f Replace the tulip_delay_300ns() with a DELAY(1). Hammering the PCI bus
to achieve a delay is pretty mean.

Andrew reports:
"The tulip_delay_300ns() is, well, bloody stupid on machines with a
heavily loaded PCI bus.  It tries to do a delay by assuming PCI reads
will take a certain amount of time & issues a large amount of
(expensive, 5% CPU when your PCI bus is heavily loaded) pci reads.

Locally, we've replaced the calls to tulip_delay_300ns(sc) in the EMIT
macros with a simple DELAY(1) and not seen any problems.  Plus we've
gained about 50Mb/sec throughput on our gigabit network cards because
of the added PCI bus bandwidth available."

Also, I do not understand why, but this change appears to stop the
Transmit Fifo underrun on one of my systems (but not the Alpha PC164SX).
This shouldn't make that much of a difference since the mii bus isn't
touched all that often, but perhaps when it does get accessed and hence
hammers the register, it was causing the chip to get upset.

579f45fa60 Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it.  Driver writers can do
this if it's not defined.  (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

84b399de51 Changes to support diskless booting on the alpha:
* Make the network code in the bootstrap more chatty (helps debugging)
* Add nfs root stuff to cpu_rootconf(). I also added a check to make sure
  it really was netbooting which allows the use of the same kernel for local
  and network boots.
* Tweak the de driver so that it takes the speed setting from the console
  for the alpha (some PWSs have broken de chipsets). This is the same
  behaviour as NetBSD/alpha.

3b419f5843 set if_snd.ifq_maxlen to something reasonable - note that if_de.c has
a wierd double-queue arrangement..  It always empties the if_snd queue
then puts the transmit packets into a different queue that is limited
by the number of TX descriptors and does it's own discards...
This should stop the boot-time XXX warning anyway.

d12895f90b Removed a bogus cast to v_caddr_t. This is part of terminating

changed one wrong cast and one harmless cast to 2 wrong casts,
and rev.1.96 only fixed the originally wrong cast.

Guy Helmer <ghelmer@scl.ameslab.gov> has given it a shot (before getting on

in the testing he was able to do.
