represent in the TCP header. The old code did effectively:
win = min(win, MAX_ALLOWED);
win = max(win, what_i_think_i_advertised_last_time);
so if what_i_think_i_advertised_last_time is bigger than can be
represented in the header (e.g. large buffers and no window scaling)
then we stuff a too-big number into a short. This fix reverses the
order of the comparisons.

Introduce the SIOC[SG]IFGENERIC hooks that can be used to pass an
arbritrary ioctl subcommand into an interface driver. Surprisingly
enough, there was no provision for this already present (except of the
option of abusing SIOC[SG]IFMEDIA for this).
The idea is that an interface driver can establish ioctl subcommands
of its own that can't be meaningfully interpreted by the upper layer
interface ioctl function. Something like this is required to
implement a clean solution of passing down things like CHAP secrets or
PPP options to the /sys/net/if_sppp* files. (Yes, my CHAP is now
finally working with it, but i gotta update my kernel to the new
callout interface before being able to commit _that_.)

I think this is safe enough to go into RELENG_2_2 as well, if there's
demand.
This driver includes the following patches submitted by:
1.0 Hideyuki Suzuki <hideyuki@sat.t.u-tokyo.ac.jp>
Japanese Cable support
2.0 Keith Sklower <sklower@CS.Berkeley.EDU>
Minor update to the BSDI section so it compiles cleanly on BSDI
3.0 Joao Carlos Mendes Luis <jonny@coppe.ufrj.br>
ioctl interface to select video format , NTSC, PAL, etc...
ISSUES:
An example and better explansion on how to specify a user's login
class in /etc/master passwd is needed.
(As I don't seem to be specifiying it right, I can't do it).
Support VJ slot id compression.
Previously, ppp would negotiate a max slot between 2 & 15
(if asked), and would agree to slot id compression (if asked).
It would then proceed to use 16 slots and no compression
anyway. The result was a rather unusable connection.
of the system to be rebuilt anyway, this is a good time to introduce
LOG_NTP.
The reasoning for a separate facility is that xntpd can sometimes
cause exaggerative log message at high prioritites which are,
depending on your environment and available clock sources, not
necessarily as important as other LOG_DAEMON messages. However, they
used to clutter log files and system console in the existing setup.
Note that this situation could not be resolved using the !xntpd option
(think about it).
xntpd(8) is supposed to automatically pick up the change, it had
already all necessary #ifdef's.
The chosen value does, as far as my inquiries yielded, not clash with
any other operating system.
Did I ever spam this file good with that last commit. Despite 3
reviewers, we still managed to revoke the eBones fixes, TCL 8.0 support,
libvgl and a host of other new things from this file in the process of
parallelizing the Makefile. DOH! I think we need more pointy hats - this
particular incident is worthy of a small children's birthday party's worth of
pointy hats. ;-)
I certainly intend to take more care with the processing of aged diffs
in the future, even if it does mean reading through 20K's worth of them.
I might also be a bit more anal about asking for more up-to-date changes
before looking at them. ;)
pointy hat last? :-]
When one is selecting (or polling) for write, it helps if we use the
write side of the pipe when requesting wakeups instead of the read side.
This broke ghostview (at least) - I'm suprised it wasn't noticed for
so long.

FAILESAFE is defined, NO_LOCK bit of CCR1 is cleared.
- CPU_WT_ALLOC enables write-through allocation.
sysctl option 'fakes' like a card was removed and inserted when the

and the old code is used.

so enable it and hope for the best.

instead of the first available, like Win95 does. This appears to help
on some machines, and avoids potential problems with built-in serial
ports which tend to live at IRQ 3, which is usually picked with the
old method.
