MFMP: Make ppp multilink capable. See the file README.changes, and re-read the man page.

o Redesign the layering mechanism and make the aliasing code part of the layering. We now ``stack'' layers as soon as we open the device (when we figure out what we're dealing with). A static set of `dispatch' routines are also declared for dealing with incoming packets after they've been `pulled' up through the stacked layers. Physical devices are now assigned handlers based on the device type when they're opened. For the moment there are three device types; ttys, execs and tcps. o Increment version number to 2.2 o Make an entry in [uw]tmp for non-tty -direct invocations (after pap/chap authentication). o Make throughput counters quad_t's o Account for the absolute number of mbuf malloc()s and free()s in ``show mem''. o ``show modem'' becomes ``show physical''.

o Log the (payload/size) of all packet types, not just TCP packets o If the new ``filter-decapsulation'' is enabled, delve into UDP packets that contain 0xff 0x03 as the first two bytes, and if we recognise it as PROTO_IP, decapsulate it for the purpose of filter checking. If we recognise it as PROTO_<anything else> mention this for logging purposes only. This change is aimed at people running PPPoUDP where the UDP traffic is being sent over another PPP link. It's desireable to have the top level link connected all the time, but to have the bottom level link capable of decapsulating the traffic and comparing the payload against the filters, thus allowing ``set filter dial ...'' to work in tunnelled environments. The caveat here is that the top ppp cannot employ any compression layers without making the data unreadable for the bottom ppp. ``disable deflate pred1 vj'' and ``deny deflate pred1 vj'' is suggested.

extern int PacketCheck(struct bundle *, unsigned char *, int, struct filter *,
Allow a ``timeout secs'' filter option to let specific packet types effect the idle timer in different ways. Submitted by: Stefan Esser <se@freebsd.org> With adjustments by me to document the option in the man page and to give the same semantics for outgoing traffic as incoming. I made the style more consistent in ip.c - this should really have been done as a separate commit.
