25ee6cca2a Clean up Ethernet drivers:
- fill in and use ifp->if_softc
	- use if_bpf rather than private cookie variables
	- change bpf interface to take advantage of this
	- call ether_ifattach() directly from Ethernet drivers
	- delete kludge in if_attach() that did this indirectly

Sorry for the delay.

6a1863f80c Set flag to stop backoff counter from counting when carrier activity is
detected. This dramatically reduces the collision rate (about 1/10th of
what is was previously).

440393bb44 From Matt Thomas:
"I screwed the initialization of the burstsize.  Right now it will default
to 0 (which can cause corruption problems on high latency PCI buses).  It
should be set to 8 longwords to avoid problems with certain PCI chipsets."

234ef116d9 Say goodbye to IFF_NOTRAILERS. Support for trailers was officially
dropped for 4.4, but for some reason this flag lived on.  (Until

d625c1c9da Fixed bugs in multicast address handling (flag was set in wrong register,
etc.). The tulip_start routine was rewritten to use less stack space (I've
been having problems with wcarchive overflowing the stack and this should
help a little). This version also has preliminary NetBSD support.

Rod Grimes helped in testing this version of the driver. Thanks Rod. It's
additionally been extensively tested here and on wcarchive.

cf998003ee There are two serious bugs in if_de.c. The first should not matter
to most users (the wrong length is passed to ether_input).  The
second is more serious.  The multicast hash algorithm uses the wrong
(low) bits instead of the right (high) bits.  This is only an issue
if you use >12 multicast addresses but if you are using IP multicast
then it might affect you...

5f72b26c0a Fixed bug in bpf/multicast support that caused multicast packets to get
thrown out if bpfilter support and no BPF listener. (submitted by Bill
Fenner)
Removed unused variable and changed another from a stack variable to a
static - the variable was a rather large array of structs that consumed
a lot of stack space. (me)

50e5eb484b 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.

b553215b12 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.

54d8522bec 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.

f89e56828a 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.

68acac5e76 Moved conversion of ether_type to host byte order out of ethernet drivers

98cbcd3a01 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
