1) if_ie.c:
Changed a printf and put a space in it. Formerly the "<3C507>"
confused the syslog. He tried to see that as the priority to
log that message.
2) isa_device.h:
Changed the iobase variable from short to u_short. EISA
Adresses can go up to 0xf000 and the sign extension doesn't
look good in the probe output. Example:
ep1 at 0xffff8000-0xffff8000f is not good :-), i like more a
ep1 at 0x8000-0x8000f.
3) isa.c:
Changed a string constant from "probe" to "prob", it gets
later already an "ed" tagged on the end.
find something useful to do other than taking credit for other people's
work. Also make the 3C507 bits match the indentation style of the rest of
the code.

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
*
