the kernel. ppp_tty.c goes to some lengths to minimise the inter-layer
calling (including a soft ISR). ppp_tty.c takes care of the soft masking
that was needed still.
(I've discovered that bugs in this area show up within an hour if the
masking was not correct.. :-} This combination has proven stable on
specialix serial ports, although there was some concern about the softtty
parts of sio/cy and netisr colliding - but Bruce has fixed that now)
set in open() when CLOCAL is set unless carrier is present.
Fixed initialization of line discipline. It lived across opens.
Lines that started with the wrong discipline probably didn't work
at all, because TS_ISOPEN is only set by TTYDISC.
if_sl and if_ppp (from ppp-2.2), eliminating the nearly identical
pppcompress.[ch] code. Add maximum VJ compression states argument to
sl_compress_init().
if_sl: call sl_compress_init() with the extra argument.
non-fatal. I've make it return an appropriate error to the caller instead
of panic()ing.
Handling an error condition is inherently more friendly than exploding
the kernel.. :-) The new behavior is a little closer to traditional
clists, potentially making porting a little simpler.

magneto-optical devices, it's scope can (and should) be widened to
cover all removable type 0 (direct) devices as well, since this class
of devices is sharing the same principles. Things like suport for
media eject etc. will be supported later. (Shunsuke is also working
on the problems arising out of the use of media with physical block
size != 512 bytes (which is not uncommon for MODs).

Make scsiconf more flexible about recognizing ``foreign'' devices.
This part needs to be rewritten some day to allow for matches whithou
strict version number checks, but either Julian as Peter seem to be
too busy right now, so i'm finally commiting the version that's
working for me stable now for several months, as an interim
workaround.

this driver hasn't been checked but as a separate module, bringing it in won't
break anything else and it't the best way of testing it......

line discipline interrupt handlers more or less expect to be called at
spltty() == splimp(), although they have internal splimp()s that are
bogus if this expectation is satisfied. They are called at splsoftty()
from many tty drivers, so they were not protected from being reentered
from their own netisrs. They certainly don't expect that but are
apparently remarkably robust if it occurs. The problem in PR 798 seems
to be caused by pppstart() being reentered and finishing off the output
in progress by following the (stale) sc->sc_outm pointer. Then the
original pppstart() finds garbage in m2 after MFREE(m, m2). slstart()
doesn't have internal state like sc_outm so reentry of it probably only
causes out of order and dropped packets.
in the FIN_WAIT_2 state in order to prevent the conn. hanging there

modularization of the wd/wcd/atapi driver is ugly.
Include cons.h from a less bogus place.
Removed an ARGSUSED. Unused args are normal for devswitch functions
and lint was informed about them for about 5 functions out of 1000.
Lint should be informed about them, if at all, in some other way.
Remove confusing backwards compatibility code that allowed driver to be
used in pre-4.4 releases. The 3COM card's use -link2 to switch tranceivers.
(no functional changes here)
This code will only be included in your kernel if you have
'options DEVRANDOM', but that will fall away in a couple of days.

The goal is to make them "user-friendly" :-)
In the end this will allow a SNMP style "getnext" function, sysctl editing
in the boot-editor and/or debugger, LKMs can define sysctl vars when
they get loaded, and remove them when unloaded and other interesting
uses for dynamic sysctl variables.
convention of having their entry point named "<modname>_mod"".
Symorder is enforcing this when the current bsd.kmod.mk is installed.
I've not tested all these, but at least they all compile now.
Reattach them to the makefile.
Note that the change that I made to symorder needs to be compiled and
installed before any LKM's will work - the last version was corrupting
the relocation tables. A "make world" will to this, but if you
manually run a make on the lkm's you'll need to take care of it by
hand.
