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.)
1) Adjust NFRAMES from 16 to 8 per 16k of memory.
2) Acknowledge interrupts to the card early in the interrupt
handler before processing the event that caused the interrupt.
This frees the card to process addtional events instead of
waiting for the driver to finish handling events.
3) Changed the initialization of the transmit buffers to be a
loop so that the number of buffers can be more easily changed.
4) Moved the code to take the adapter out of loop back mode to just
before we enable the receiver.
I also made the driver dynamically size its resource arrays at attach
time so that we can take full advantage of adapters with more than 16k
of memory.
Richard has some other changes he's working on to improve performance,
but this should get ee16 support working reliably again.

Removed ifnet.if_init and ifnet.if_reset as they are generally unused.
Change the parameter passed to if_watchdog to be a ifnet * rather than
a unit number. All of this is an attempt to move toward not needing an

the driver softc.

Changed some of the argument passing to some functions to make a little
more sense.
if_ep.c, if_vx.c:
Killed completely bogus use of if_timer. It was being set in such a way
that the interface was being reset once per second (blech!).

This is a bulk mport of Mike's IPX/SPX protocol stacks and all the
related gunf that goes with it..
it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..

For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago). For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device. The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out. A few bytes saved by using
%b to format the features list rather than lots of ifs.
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.
and all SCSI devices (except that it's not done quite the way I want). New
information added includes:
- A text description of the device
- A ``state''---unknown, unconfigured, idle, or busy
- A generic parent device (with support in the m.i. code)
- An interrupt mask type field (which will hopefully go away) so that
. ``doconfig'' can be written
This requires a new version of the `lsdev' program as well (next commit).
Add initialization to the if_ie driver for the Micom Interlan NI5210 card.
This is a very old 82586 based card with only 8Kb or 16Kb on board memory.
Also only 8-bit wide instead of 16-bit like the AT& or 3COM card.
Warning: this thing is only tested so far that it detects all bits
correctly but is not yet on an ethernet. Will do that tomorrow.

Adresses can go up to 0xf000 and the sign extension doesn't

Add the 3com 3C507 card to the if_ie.c driver. The files elink.c and
elink.h are helding routines that are shared between the 3C507 and the
3C509/3C579. if_ie507.h are constant declarations unique to the 3C507.
The code is based on the NetBSD driver if_ie.c donated to NetBSD by
Rafal Boni and then modified by Charles Hannum.
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.
This also includes support for second-directory compiles. This is not
quite complete yet, as `config' doesn't yet do the right thing. You can
still make it work trivially, however, by doing the following:
rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
make
change all of these to be timeout_funt_t and remove the casts and
typedef?
Remove secound argument (uban) from ifp->if_reset routines since it is now
obsolete.

Okay, I tracked down the d*mn thing that is causing the memcpy to be
emmitted by gcc2. In the following patch is a fix to eliminate the
one place that was causing gcc to do the memcpy in function ie_readframe
for the ie_recv_frame_desc rfd = *(ie->rframes[num]) structure copy.
I also fixed the code so that the NS (XNS) support would compile with
out error and removed the cruft #define ns_* stuff from the softc
structures (I did this a while back for all the other either drivers)
Removed the $Log$ and all of the old log stuff, that is all kept in
the cvs tree, no need to duplicate it in the file... I'll copy it
into my commit message so that it is all retained, except the
revision numbers are going to get screwed up.
It now compiles cleanly under my LINT kernel...

$Log$ stuff from Garretts original file
* $Log$
* Revision 1.32 1993/06/20 15:56:15 wollman
* Fixed warning message.
*
* Revision 1.31 93/06/20 15:52:28 wollman
* More compilation lint.
*
* Revision 1.30 93/06/20 15:48:16 wollman
* Commented all the rest of the cast-qual warnings. Might be
* fixed someday by changing the prototypes of bcopy(), bzero(), etc.
*
* Revision 1.29 93/06/20 15:40:13 wollman
* Started fixing some of the cast-qual warnings (most just commented).
*
* Revision 1.28 93/06/12 20:39:14 wollman
* Changed definition of MK_24 to silence -Wcast-qual.
*
* Revision 1.27 93/06/08 17:05:57 wollman
* Attach routine now returns void.
*
* Revision 1.26 93/06/08 16:31:21 wollman
* Deleted attempt to set watchdog timer, since we don't use it.
*
* Revision 1.25 93/04/16 22:15:31 wollman
* Fixed infinite loop in iestart() which would cause the transmitter
* to constantly step on the Ethernet, sending the same two packets over
* and over again. This crashes the router (really!) and makes other
* network users very angry.
*
* Revision 1.24 93/04/14 23:57:47 wollman
* Increased transmit buffer size from 1504 to 1512, just in case I don't
* understand how the MTU is used.
*
* Revision 1.23 93/04/14 23:16:19 wollman
* Fix iestart() so that it only tries to execute a command if one was
* queued up (oops...).
*
* Revision 1.22 93/04/14 23:02:16 wollman
* Unknown changes.
*
* Revision 1.21 93/04/12 18:29:33 wollman
* Added multiple transmit commands. Note that they are always queued in
* pairs (there are only two to begin with), and the I flag is only set
* on the second one. This should decrease interrupt activity somewhat.
*
* Revision 1.20 93/04/12 15:36:05 wollman
* Changed setup of config block to take into account difference between
* StarLAN (10BASE-T) and Ethernet: StarLAN is Manchester, Ethernet is NRZ.
*
* Revision 1.19 93/03/23 18:58:44 wollman
* Raised count of receive buffers from 32 to 48 and included analysis of
* memory usage in a comment near that definition.
*
* Revision 1.18 93/03/18 03:59:53 wollman
* Last try to get large TCP windows to work...
*
* Revision 1.17 93/03/18 03:54:10 wollman
* Added RNR processing as a part of receive interrupts. Hopefully this
* will make everything Just Work now.
*
* Revision 1.16 93/03/18 03:23:24 wollman
* Still having problems with RNR conditions. Basic problem: say we
* set TCP window to 16k, which is a semsible value. Then smart
* partners will blast 16k to us, of which we can fit 8k minus a bit
* into our buffers. (Need to look at that memory map..) So, we get
* an RNR interrupt. The problem is, what do we need to do in this case?
* The original code doesn't work, but it doesn't hang the system either.
*
* Revision 1.15 93/03/18 02:37:00 wollman
* Disabled watchdog timer. This gets called from a timeout somewhere,
* which is running up at softclock. This is at a higher priority than
* we are, so we can get interrupted in the process of receiving something
* by the timer expiration, which is not a nice thing to have happen.
* Question: how can we keep this functionality, but do it in sync with
* our interrupts? (Ugh!)
*
* Revision 1.14 93/03/18 02:35:46 wollman
* Fixed some more problems with receive code---it works!
*
* Revision 1.13 93/03/17 20:15:59 wollman
* Think we fixed the serious (showstopper) bugs in 1.12.
*
* Revision 1.12 93/03/15 17:45:39 wollman
* Changed filtering logic dramatically to avoid the unnecessary copyin
* for BPF or multicast routing when the packet is not for us. (We
* have to run in promiscuous mode in this case.) We still need to
* deal with the problem of allocating one mbuf per receive buffer;
* we should be able to get away with a single mbuf for all reasonable
* incoming packets, and using an mbuf cluster will help avoid unnecessary
* copying of data.
*
* Revision 1.11 93/01/30 20:23:15 wollman
* Fiddled with reset code to hopefully make it work better when the
* watchdog timer expires. Question: why does it make a difference that
* we do the same thing through ieioctl() as we were doing before. The
* old code, when iereset() was called, the receive unit would completely
* die. But, a cycle of ifconfig ie0 down ; ifconfig ie0 up' would bring
* things back to normal. So, we try to mimic that now. Grrr...
*
* Revision 1.10 93/01/29 17:26:50 wollman
* Finally fixed multicast routing/BPF mb_map full problem!!!!
* It turned out that, when we received a packet not for us, we
* would just return from ie_readframe(), *WITHOUT* freeing the
* mbuf that the packet was in. So, when running in promiscuous
* mode (i.e., multicast routing or BPF without -p), we would have
* (on our extremely busy subnet 4) a memory leak of epic proportions.
*
* We now hold on to a single mbuf chain allocated in this way,
* and the next time a packet is read, we free it. Also, the
* next time a packet is transmitted, we free it. This way,
* we never lose more than 6 mbufs total (and on average more like
* 3).
*
* Revision 1.9 93/01/23 14:22:21 wollman
* Added some StarLAN Fiber modifications from L. Jonas Olsson.
*
* Revision 1.8 93/01/23 14:02:34 wollman
* Added support for IP multicasting.
*
* Revision 1.7 92/11/21 17:51:59 wollman
* Added StarLAN Fiber version point to my driver.
*
* Revision 1.6 92/11/20 18:21:45 wollman
* Fixed documentation, made out-of-mbuf condition an error.
*
* Revision 1.5 92/11/20 18:14:02 wollman
* Move change of ethertype to host byte order so that it's after
* bpf_mtap. Hopefully, this will allow us to listen to incoming
* IP packets.
*
* Revision 1.4 92/11/20 18:11:00 wollman
* Added code to drop packets when we run out of mbufs rather than
* panicking. This should alleviate the problems observed when using tcpdump.
*
* Revision 1.3 92/11/14 14:12:40 wollman
* Added BPF support code.
*
* Revision 1.2 92/11/14 13:30:26 wollman
* Added RCS keywords
