8e718bb4af When adding a route, set rt_ifa and rt_ifp a little earlier so that
the protocol-specific add routine can examine it if desired.

78988ab839 PR #kern/600: PPP does not pay attention to IPTOS_LOWDELAY
Kernel PPP doesn't pay attention to IPTOS_LOWDELAY, but uses
        a table of port numbers, which isn't a generic method.  The following
        patch fixes this (the table is still used, but in addition
        PPP queues the packet in fastq if IPTOS_LOWDELAY is set.

93ff4e36e3 Modified joerg's last change to only set the interface "up" when setting
the address if the device is a SLIP device (i.e. "attached").

1394aff0cd Revision 1.21 of if_sl.c broke the traditional behaviour that
assigning an address to an interface automatically marks this
interface IFF_UP.  The fix corrects this (and closes PR sys/577).
This is consistent with the way ethernet interfaces are being handled.

523a02aa7a Don't skip point-to-point interfaces if the netmask==0 (the netmask
should be completely ignored for point-to-point interfaces).
For point-to-point interfaces, route based on the destination address,
not the local address.

2cd67fdafd 1) Set interface up/down correctly as a function of open and close of the
SLIP device.
2) Don't directly frob the IFF_UP flag - use if_up/if_down as it was
   intended.
3) Return ENETDOWN if IFF_UP isn't set when outputing, drop the packet if
   if IFF_UP isn't set when inputing.

David Greenman
b2af64fd03 Added a fix for a bug which caused the wrong interface to be selected
for broadcasts if point-to-point links shared the same IP address as
the ethernet. The fix must be enabled with P2P_LOCALADDR_SHARE option
in the kernel config file. This will someday likely be standard, but
there isn't sufficient time before release to determine if there are
any interoperability problems with routed and/or gated.

cd02a0b741 Finally finish the cloning cleanup work by making sure that clones
go away whenever a clone's parent is changed, or a route is added in a
certain set of circumstances.

This also includes code to forbid setting a route's gateway to an
address which can only be reached through that route, thus (hopefully)
eliminating one class of cloning bottomless-recursion bugs.

so that these ioctls can be handled by the calling layer(s).

- include the appropriate header to declare an implicitly declared function.
- declare timeout functions correctly and remove numerous bogus casts that
  hid (but didn't fix) their incorrectness.

b4fff2ae1a Patch from Greg Ansley:
In rare cases, when the filter specified accesses an multi-byte value that
is split across mbuf's, the value loaded is incorrect.  And if you are very
unlucky (like me) it will index off the end of the mbuf and into an
unallocated page and panic the system.

If you look at the code you will discover the the index *k* is added to
the pointer *cp* and the used AGAIN as a subscript.

ca9301398c This sl enhancement helps to keep serial line (modem) connection alive.
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.

   o Fixing bug for Predictor-1 function.
   o Add new parameter that re-sent interval for set timeout commands.
   o Improving RTT (Round Trip Time) and reducing processor time.
     - Previous Timer service was using polling, and now using
       SIGALRM ;-)
     - A 0.94beta2 will not work correctly....

   -- Follows are additinal feature not including 0.94beta2
   o Support Proxy ARP
     - add "enable/disable proxy" commands
   o Marging common routine in CHAP/PAP.
   o Enhancing LCP/IPCP log information.
   o Support local Authfication connection on port 300x and tty.

     - add "passwd yourpasswd" commands
   o Support afilter - keep Alive filter that a packet can send/receiving
