respectively. Most of the longs should probably have been
u_longs, but this changes is just to prevent warnings about
casts between pointers and integers of different sizes, not
to fix poorly chosen types.
- connector selection values (should fix aui/bnc),

- interrupt mask adjustments,
- add some brackets where a #ifdef could break an if(),

or unsigned int (this doesn't change the struct layout, size or
alignment in any of the files changed in this commit, at least for
gcc on i386's. Using bitfields of type u_char may affect size and
alignment but not packing)).
FreeBSD/alpha. The most significant item is to change the command
argument to ioctl functions from int to u_long. This change brings us
inline with various other BSD versions. Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.
The prototype FreeBSD/alpha machdep will follow in a couple of days
time.
This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway. Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug. The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(
This commit move struct arpcom from <netinet/if_ether.h> to
<net/if_arp.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.)
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.
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.

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. :-)

changes relative to the 2.2 compatable version are include file
related, the new multicast interface (!) and the new PCI interface.
This should work "as-is" but has not been tested (I have not been able
to get a dc21x4x based card for testing).
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
previous hackery involving struct in_ifaddr and arpcom. Get rid of the
abominable multi_kludge. Update all network interfaces to use the
new machanism. Distressingly few Ethernet drivers program the multicast
filter properly (assuming the hardware has one, which it usually does).
a) Removal of private typedefs tulip_uint*_t, use standard u_int_*_t.
b) Change [Dd][Cc]21.4. to just 21.4., seems Dec has done this to all
of the drivers for all OS's. (Did they get in trouble with someone?)
[The few that remain can either not be eliminated, or are waiting for
additional driver functional changes that will remove them.]
c) Move some code from dc21040.h into the driver, later a whole block of that
code and more will move to devar.h, but for now this makes it easier
to study diffs.
d) Add a big bold comment to the README.de file about it not reflecting
reality anymore.
Note that these are all cosmetic changes and should be no functional
change in the driver whatsoever. If _anyone_ spots a problem introduced
by this please let me know ASAP!

I spent the better part of a day trying to figure out why my
experiment didn't work the way I expected, only to find out that
the router was dropping huge numbers of packets because of PCI bus
priblems. This does not fix the bug that errors are counted as
input packets because my patch doesn't apply cleanly.
- 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

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.

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...

ether_input want it another way. Ripped out trailer support from the few
remaining drivers that still had it.
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

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.
