9b3fdc5a9f Fixed mbuf leak and panic that occurred when packets got too memory
fragmented.
Added support for Cogent em100 boards.
Fixed bug that caused BPF to toggle the card to UTP.
Various other improvements.

fe16ad72f3 Matt says that no pre-2.3 pass boards were supposed to ship, but I certainly
got a 2.2 version DC21040 chip in my SMC ethernet card!  He suggests bumping
the check all the way down to 2.0 since it's pre-2.0 we're actually guarding
against.

29b4e57966 From Matt Thomas: Added support for 100Mb cards (such as the DEC DE-500-XA
and SMC 9332).

cb09d35cb0 Added a new field to the pci_device struct called pd_shutdown to specify
a device specific shutdown routine for devconf. Assign the value of this
to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.

11098d3bad Prepare for shared interrupts (required by the new PCI code that adds
support for PCI PCI bridges, e.g. found on 4ch. Ethernet cards).

95b44faffd Turn on "Capture Effect" avoidence. This modifies the collision algorithm
so that the interface won't have the effect of blocking other senders
during bulk transfers (i.e. hogging the ethernet). It improves performance
in all of my tests by reducing collisions and I believe it to be a Good
Thing.

6398cf3113 Reapplied all of Stefan's changes. What a mess - the files were modified
and moved at the same time. This made it *very* difficult to fix the
revision log lossage that happend when the files were moved. SIGH.

d33095d2b2 The physical memory allocated for input DMA must be contiguous. The driver
worked in the past only because of good fortune. Anyway, use the contig alloc
routine I wrote awhile ago (vm_page_alloc_contig) for the sound code to do
this allocation. Also, specify read+write on the permissions to pmap_enter().
Specifying just read can have unexpected consquences.

89384ace85 Fix bug I introduced that broke BPF support. Caused by a byte order problem
in an if () expression. Problem fixed by removing the test for ETHERTYPE_*
before passing packet to higher layers.

307d80be7a Moved conversion of ether_type to host byte order out of ethernet drivers
and into ether_input(). It was silly to have bpf want this one way and
ether_input want it another way. Ripped out trailer support from the few
remaining drivers that still had it.

b83f4f55d8 Bunch of fixes from Matt Thomas:
1) make #includes correct
2) fix bugs in address check macros
3) fixed bugs in, and enabled, recopy if heavily fragmented code
4) moved call to bpf tap to be before enqueing packet (probably gratuitous)
5) fixed bug that caused "abnormal interrupt" at boot time/first use
6) added support for reading Zynx address ROM
7) fixed bug that caused broadcasts to not work shortly after booting (only
	manifested if not using multicast - e.g. not in FreeBSD 2.0)
8) fixed spelling errors in comments

07d0d0fc9c Added support for SIOCSIFMTU ioctl. Fixed bug that caused panic at boot time
related to interrupts being enabled before the device attach. The interrupt
should be mapped *after* the device attach.

e754e0f30f Fixed bug that somehow made it into here: the ifp must be stored in the
mbuf header for received packets. Minor performance optimizations. Removed
#ifdef MULTICAST's as this isn't optional in our kernel.

Bug fixed, that caused system hang on first interrupt on some motherboards.

New version of PCI bus configuration code, now supports dynamic interrupt
configuration (using BIOS supplied values).
NCR SCSI and DEC Ethernet driver patched to use this feature.
*** Remove PCI IRQ specifications from your kernel config file ! ***

24161ef88f Add Matt Thomas's DC21040 PCI Ethernet driver. (This is turning out
to be quite a popular chip, so expect to see a number of products
based on it.)
