A GRE Tunnel for NetBSD

This is a very alpha implementation of GRE packet encapsulation.
Generic Route Encapsulation (GRE) is described in RFC 1701 and 1702.
The interface also supports IPIP (protocol 4) encapsulation,
as described in RFC 2003 and MOBILE (protocol 55) as of RFC 2004 but
The interface also supports MOBILE (protocol 55) as of RFC 2004 but
default is GRE mode.
Basically GRE allows to tunnel not only IP over IP, but also provides

This implementation is (as said) still alpha, but works for me.
Successful testing has been done for GRE encapsulation with Cisco routers
and NetBSD boxes as remote and with Cisco routers and Linux 2.0.35 for
IPIP encapsulation.

GRE RFC not yet fully implemented (no GRE options), no other protocols
yet than IP over IP.
RFC 2003 also not yet fully supported wrt. options etc.
Code quality is surely not best and possibly not near anything like KNF
