FreeBSD has sys/net/if_sppp.h and sys/net/if_spppsubr.c, which I'm about
to port to NetBSD. They use it for three different HDLC card drivers
and we just started using it for SyncPPP over ISDN in the FreeBSD version
of BISDN. The NetBSD version will follow shortly, so we (the BISDN team)
do need a similar framework for NetBSD. It would be cool if this could be
used for Localtalk as well!
