64bit counters are needed to simplify traffic accounting and
reduce system load at the big PPP concentrators.

node would send every outgoing frame to the "compress" hook.
Packets received on the "compress" hook were expected to be
compressed and PROT_COMPD tag was put on them unconditionally.
After this commit an alternative compression mode can be set.
In this mode the node doesn't put the PROT_COMPD, the compressor
should put it itself. This is important for such kind of
compressors, that can submit uncompressed frames.
Before this commit, if the decompression is enabled, the ng_ppp(4)
node would send and incoming frame to the "decompress" hook
only if it has the PROT_COMPD proto tag on it.
After this commit an alternative decompression mode can be set.
In this mode the node sends all the incoming packets to the
decompression hook. This is important for such kind of compressors
that need uncompressed packets too, to keep their library in sync.
These new features will be used in new version of mpd4, and in new
compressor nodes.

simply things a bit by getting rid of 'struct ng_parse_struct_info' which
was useless because it only contained one field.

NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.
This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.
Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.
See /usr/share/examples/netgraph/ngctl for an example of using this.
Also give ngctl(8) the ability to print out incoming data and
control messages at any time. Eventually nghook(8) may be subsumed.
Several other misc. bug fixes.

This is one piece of the grand unified PPP daemon concept, whereby using
netgraph nodes enables PPP data to be handled completely in kernel land,
while leaving negotiation/control to be handled by a single user land
daemon, no matter what the link type(s).
This is a safety checkin only; it compiles, but is utterly untested.

Been in production for 3 years now. Gives Instant Frame relay to if_sr
and if_ar drivers, and PPPOE support soon. See:

for on-line manual pages.
