c5f944ee5a Fixed bug that was fixed in 1.28.2.1/1.29 a little differently; the
difference is more or less cosmetic.

0063696232 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.

87c15d9649 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...

f8141f6f97 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)

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.

bbf437ee54 Mask the call to ahc_attach with an splbio/splx pair. This allows us
to poll succesfully even if we are sharing the interrupt.

Register the interrupt handler before the attach.

This commit makes the 294x PCI shared interrupt compliant.  This has
been tested with an aic7870 motherboard controller and a 294x in the
same machine shareing an irq.

f0d47944e2 Forward-declare kern_devconf for use in a prototype. Some drivers
include <pci/pcivar.h> without including <sys/devconf.h> and other
drivers include <pci/pcivar.h> before including <sys/devconf.h> if
certain identifiers are defined.

The devconf headers have convoluted interdependencies.  <sys/devconf.h>
includes <machine/devconf.h> which includes <pci/pcivar.h>.  Most
drivers include <sys/devconf.h> so even isa drivers depend on
<pci/pcivar.h>.  For similar reasons, most drivers depend on another
pci header, on an isa header and on two scsi headers.

8673e05a9a Completely new PCI code:
1) Supports PCI to PCI bridge devices (and tries to initialise them,
   even if the BIOS is brain dead).
2) Supports shared PCI interrupts. Interrupt handlers now MUST return
   '0' if they found nothing to do, '1' otherwise.

New features tested with i486 systems based on the Intel Saturn and
a DEC 4channel Ethernet card only, but expected to work on most systems.

The option PCI_REMAP has been removed !

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.
