- Report valid residual byte counts. We actually pause the sequencer
when the residual is non-zero. I thought about using DMA to do this,
bus sequencer program space is tight.
- Fix embarassing off by one error in the computation of a 2's
compliment variable. This was most likely the cause of the
many problems reported with the tagged queuing code.
- Handle "MAX_SYNC" as a special case (ie we are the ones starting
the sync negotiation sequence). This was done so that the target
scratch area can be initialed to 0 offset (asyncronous transfers)
safely. The initialization to 0 (was 15) is necessary since in
some cases a Wide negotiation could run into problems if SCSIRATE
was set wrong and we went into data(in/out).
- Trim the DMA routines a little by using some procedures. Net
effect is more functionality with 3 less instructions after this
update.
- Toggle the WIDEODD bit of the DFCNTRL whenever this is not the
last SG block. It has no effect in the 8bit bus configuration,
but in the Wide configuration ensures that the overlap byte is
held in the SCSI block if the transfer is odd so it will end
up in the next SG (the correct behavior).
- catch the interrupt type (EDGE/LEVEL) before chip reset instead
of guessing the right type.
- Add pause variable to the ahc struct to better handle the different
interrupt types and pausing the sequencer.
- CLRINTSTAT -> CLRSCSIINT: This is a documented bit in the CLRINT
register in newer Adaptec documentation, so use their name for it.
- Report valid residual byte counts.
- Don't mess with the target scratch areas > id 8 on single, narrow,
channel devices. The BIOS does a checksum of this area and can
flip out if we zero it out.
- Initialize the sequencer FLAGS scratch ram variable in the single
channel devices to 0. This was the cause of the annoying warning
where we would get a cmdcmplt the first time we did any type of
transfer negotiation with no valid scb. It also fixes the problem
that looked like the INTSTAT register wasn't clearing fast enough.
This only showed up on 294x cards, not motherboard aic7870s.
- Add the AHC_AIC7870 type and use it as the superset of aic7870
based controllers.
- clear the sync offset section of the targ scratch area so that
we default to asyncronous transfers. This was only a problem
for wide controllers because there was a scenario where the
offset wouldn't get updated before a data(out/in) phase would
occur. This required some change in the sequencer code since we
were depending on this field to hold the rate to negotiate.
- allow sync and wide negotiated commands to be tagged (the sequencer
now handles this properly).

I'm not exactly sure why all the inb/outw stuff got added to netboot.h
and I'd be happy if someone like Martin or Bruce could take a look at it!

Etherlink III 'zp' on 2.0R, but it did not work with the -current.
Noriyuki Takahashi <hor@aecl.ntt.jp> san has fixed this bug.
Our alpha-testers are tested this driver with 3C589B-COMBO and
3C589B-TP. And it works fine.
I also fixed a little about the use of ZP_DEBUG symbol and beautified
the awful Frankenstein-style indent :-) with "indent -c0 -nfc1 -i4".

that ypxfr is supposed to log messages to /var/yp/ypxfr.log if it exists,
using syslog() makes more sense, especially since ypserv does the same
thing already. Try to use stderr by default, and use syslog() if stderr
is not a tty.
Also update the man page to reflect this change.
It is common case when modem hangs with carier on but don't
receive anything from another side.
This thing commonly healed with hangup and redialing.
Enhancements below allows to determine when such action
is needed and inform attach program with SIGURG signal.
There two ioctls set: outfill and keepalive, used from both
sides of connection. Outfill repeatedly sends FRAME_END with
specified timeout (i.e. 40 seconds). It is needed to get input on
other side even if no user activity on slip line currently.
Keepalive checks FRAME_ENDs from other side, and if no one
got in specified timeout (i.e. 60 seconds, max modem retrain time),
send SIGURG to attach program.
I plan to add code to slattach to handle this thing too.

restore but really didn't do it.
Restore message from old rc about configuring syscons whith
echo added before it to go to new line after "echo -n xtend" f.e.
and similar stuff.
changes to it based upon other outstanding bug reports and commits made
after his work.
Comments:
(a) sysconfig is still used to do all configuration. I was not going to
change that out from under you.... a user never need edit netstart
or rc* unless they're being very weird.
(b) rc.maint has been folded back into rc. It is just unworkable as
a separate chunk because of ordering bogosities
(c) netstart does what it says... it starts up enough of the network to
get up, it doesn't start every bloody daemon that might talk to a
socket... netstart ifconfig's the devices and sets up routing if
configured to do so.
(d) nfs disks are mounted immediately after netstart completes
(e) syslog is started as early as possible (right after nfs) so that error
messages can get logged to remote syslog servers properly
(f) named is started (there is an argument that says that named should be
started before syslogd because if you are the dns server for your domain,
you'd like named to resolve remote hosts in syslog.conf, but this is
a minority case and the trivial workarround is to put the syslog host
in /etc/hosts or use an /etc/resolv.conf -- why? because you want syslog
to catch named errors, which is a MUCH more important and likely occurance)
(g) NOW all of the rest of the network daemons such as the time stuff, RPC,
NIS, NFS, Kerberos and inetd are started
(h) the rest of the generic stuff is done (cron/printer/sendmail)
(i) shared libraries are set
(j) /etc/rc.i386 is run (this does FreeBSD/386 specific stuff like ibcs2,
xtend, and all of the syscons stuff
(this is actually started as /etc/rc.`uname -m`
(k) the syscons stuff has gotten a serious cleaning to make it consistent
with rc conventions
(l) rc.local has had the comments about syscons removed (they are not relevant
to this file now) and the full name of the kernel has been restored to
/etc/motd

NIS maps (get rid of extraneous slash a la /var/yp//domainname).
Have ypxfr log all output to /var/yp/ypxfr.log if stdin is not a
tty. This should allow logging to be done when ypxfr is called from
inside ypserv in response to a yppush request.
Update man page to reflect the change (and fix a typo).
