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.

This is consistent with the way ethernet interfaces are being handled.

For point-to-point interfaces, route based on the destination address,

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

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.

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).
Clean up the recently added code:
- 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.
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.
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.
