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.

- Don't abuse module names to facilitate ifconfig module loading;
  such abuse isn't really needed.  (And if we do need type information

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.

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.

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.

runtime load capability, and these DATA_SET's keep getting in the way.)

430df5f4b7 Throw options IPX, IPXIP and IPTUNNEL into opt_ipx.h.
The #ifdef IPXIP in netipx/ipx_if.h is OK (used from ipx_usrreq.c and
ifconfig.c only).

I also fixed a typo IPXTUNNEL -> IPTUNNEL (and #ifdef'ed out the code
inside, as it never could have compiled - doh.)

b4a051f1d8 Merge in changes from Matt. Accton EN12xx support, bugfixes. There is
a change that might have an effect on the problems some have seen
with older chips, it looks like the driver may have mistakenly thought
there was an SIA when there isn't.

385e745e02 Import Matt's current de driver... He appears to be maintaining it in
the NetBSD source tree now.  This is slightly newer than the updated
.tar.gz on the 3am-software web site.

4a595144c0 ``oops''. I cut/pasted the original free()'s based on mark's suggestion
rather than extracting the diff from Mark's patch, but it turns out that
I was freeing one allocation twice due to a previous cut/paste braino.
My botch, not Mark's.

09575ecacc Missed a place where the extra descriptor buffers would need to be
freed.

28c412b0e9 malloc() the rx and tx descriptors seperately rather than as part of the
large (over 4KB) softc struct.  The descriptor array is accessed by
busmaster dma and must be physically contiguous in memory.  malloc() of
a block greater than a page is only virtually contiguous, and not
necessarily physically contigious.

contigmalloc() could do this, but that is a bit on the overkill side.

I'm not sure of the origins of the problem report and diagnosis, I learned
of the problem via mail forwarded from  Jim Shankland <jas@flyingfox.com>.

Jim said that Matt Thomas's workaround was to reduce the number of
transmit descriptors from 128 to 32, but I was concerned that it might
cost performance.  Anyway, this change is my fault, not Jim's. :-)
