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".

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.

update what has actually been touched. This should speed up
screen access on slow hardware.
Introduced setting of "destructive" cursor size, much like
the old hardware cursor.
on a "NQNFS" kernel config option. NQNFS is a 4.4 wart and the performance
penalty of the lease checks on the client/server for _local_ I/O is too high
to have this occur all the time - especially when most people will never
use it.

1) Preserve old buffer contents when input buffer overflows.
Old code clear buffer and rewrite it again, if !MAXBEL
(for MAXBEL it does right thing :-).
F.e. if you type too long string, last chars passed,
not first ones as expected.
Moreover, it flush output queue too in this case without any needs.
2) Don't do IXOFF, if IGNCR and c==\r, ignore completely.
3) If PARMRK is active and !ISTRIP and char == 0377
put yet one 0377 to distinguish it from parity mark sequence.

Term "correctly" assumes POSIX spec. and 4.4 ttyinput() behaviour.
1) Discard BREAK/parity at interrupt level when apropriate IGN*

- ignore the partition table if it is identical with the bogus one in

(1) allow C = 1023, H = max, S = max.
(2) allow C to be correct modulo 1024.
Other compatibilty cruft weakens the error handling to allow all

- distinguish primary partition table from extended partition tables.
- don't use diskerr() except for i/o errors.

gets rids of the bogosity that you can call the routine without
having the vnode locked. The changed vnode_pager_umount properly locks
the vnode before calling vnode_pager_uncache.
It was previously after the VOP_RENAME and the reference and lock on
the vnode had already been lost, allowing interesting internel
inconsistencies. This is one of the two reasons why freefall was crashing
every hour or two (the other being nullfs bugs).
Don't call vnode_pager_uncache in revoke(). revoke() is only allowed on
