2edde8a2bb Implement timestamps so i4b/driver/i4b_isppp.c can derive the idle
time from the PPP packets sent.  This effectively merges rev 1.2 of
the old i4b_ispppsubr.c, with the exception that i eventually ended up
in debugging and fixing it so the idle time is now really
detected. ;-)  (The version in i4b simply doesn't work right since it
still accounts for incoming LCP echo packets which it is supposed to
ignore for idle time considerations...)

d18dbbbe9a Break out the relevant fields from struct sppp into a struct
sppp_parms that are needed for the SPPPIO[GS]DEFS ioctl commands.
This allows it to keep struct sppp inside #ifdef _KERNEL (where it
belongs), and prevents userland programs that wish to include
<net/if_sppp.h> from including the earth, the hell, and the universe
before the are able to resolve all the kernel-internal stuff that's in
struct sppp.

c3e53c63c1 Make the LCP restart timer configurable.
This (effectively) merges rev 1.36 of i4b's old if_spppsubr.c, albeit
in a slightly different manner (we export the timer in millisecond
values as exposed to tick values from/to userland).

5a94a8f0c9 Implement VJ header compression for sppp.
This is the logical merge of rev 1.32 of i4b's old if_spppsubr.c (which
was based on PR misc/11767), plus (i4b) rev 1.6 of i4b's if_ispppsubr.c,
albeit with numerous stylistic and cosmetic changes.

70547e89ed Don't log RXJ+ protocol rejects unless we are in debug mode. (RXJ-

eb6c6922fc For SIOCSIFADDR, don't call if_up() since it would attempt to add the
route to the destination twice.  Now that brian has fixed route.c to no
longer accept this second route, this long-standing nuisance became a
showstopper bug for sppp users.

In retrospect, this is the same fix as the one in rev 1.78 of if_sl.c;
most likely the original version of sppp has been cloned from SLIP. ;-)

96902e811b Only call rt_getifa() if we've either been passed a gateway or
if we've been given an RTA_IFP or changed RTA_IFA sockaddr.

This fixes the following bug:
  >/dev/tun100
  >/dev/tun101
  ifconfig tun100 1.2.3.4 5.6.7.8
  ifconfig tun101 1.2.3.4 6.7.8.9
  route change 6.7.8.9 -ifa 1.2.3.4 -iface -mtu 500
which erroneously changed tun101's host route to have an ifp of tun100
(rt_getifa() sets the ifp after calling ifa_ifwithnet(1.2.3.4))

69c3d327d1 Make bpf's read timeout feature work more correctly with
select/poll, and therefore with pthreads.  I doubt there is any way
to make this 100% semantically identical to the way it behaves in
unthreaded programs with blocking reads, but the solution here
should do the right thing for all reasonable usage patterns.

The basic idea is to schedule a callout for the read timeout when a
select/poll is done.  When the callout fires, it ends the select if
it is still in progress, or marks the state as "timed out" if the
select has already ended for some other reason.  Additional logic in
bpfread then does the right thing in the case where the timeout has
fired.

Note, I co-opted the bd_state member of the bpf_d structure.  It has
been present in the structure since the initial import of 4.4-lite,
but as far as I can tell it has never been used.

f8ad22919e Device Polling code for -current.
Non-SMP, i386-only, no polling in the idle loop at the moment.

To use this code you must compile a kernel with

        options DEVICE_POLLING

and at runtime enable polling with

        sysctl kern.polling.enable=1

The percentage of CPU reserved to userland can be set with

        sysctl kern.polling.user_frac=NN (default is 50)

while the remainder is used by polling device drivers and netisr's.
These are the only two variables that you should need to touch. There
are a few more parameters in kern.polling but the default values
are adequate for all purposes. See the code in kern_poll.c for
more details on them.

Polling in the idle loop will be implemented shortly by introducing
a kernel thread which does the job. Until then, the amount of CPU
dedicated to polling will never exceed (100-user_frac).
The equivalent (actually, better) code for -stable is at

	http://info.iet.unipi.it/~luigi/polling/

and also supports polling in the idle loop.

NOTE to Alpha developers:
There is really nothing in this code that is i386-specific.
If you move the 2 lines supporting the new option from
sys/conf/{files,options}.i386 to sys/conf/{files,options} I am
pretty sure that this should work on the Alpha as well, just that
I do not have a suitable test box to try it. If someone feels like
trying it, I would appreciate it.

NOTE to other developers:
sure some things could be done better, and as always I am open to
constructive criticism, which a few of you have already given and
I greatly appreciated.
However, before proposing radical architectural changes, please
take some time to possibly try out this code, or at the very least
read the comments in kern_poll.c, especially re. the reason why I
am using a soft netisr and cannot (I believe) replace it with a
simple timeout.

ecb4d3d05f Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.
Have sys/net/route.c:rtrequest1(), which takes ``rt_addrinfo *''
as the argument.  Pass rt_addrinfo all the way down to rtrequest1
and ifa->ifa_rtrequest.  3rd argument of ifa->ifa_rtrequest is now
``rt_addrinfo *'' instead of ``sockaddr *'' (almost noone is
using it anyways).

Benefit: the following command now works.  Previously we needed
two route(8) invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0
