PPP is a mechanism for encapsulating arbitrary protocol packets over a serial
link. However, the ppp driver in Linux won't take arbitrary protocols, just the
ones it knows about like say IP and Novell IPX, and a few others.
Packets belonging to protocols that the ppp driver does not recognize
are forwarded to the daemon rather than to the networking subsystem.
The daemon sees the unclassified packet and generates a syslog message.
Is that clear as mud? :)
Look in /include/linux/ppp_defs.h for some PPP protocol numbers.
Unfortunately, these don't correspond to the numbers used in ethernet.
