/* $NetBSD: in6_gif.h,v 1.11 2005/12/10 23:39:56 elad Exp $ */
sync gif interface code with latest kame. IFF_RUNNING is clearified. attach/detach logic is more clearner. the old code mistakenly set IFF_UP by itself, now the behavior is gone.

introduce sys/netinet/ip_encap.c, to dispatch inbound packets to protocol handlers, based on src/dst (for ip proto #4/41). see comment in ip_encap.c for details of the problem we have. there are too many protocol specs for ip proto #4/41. backward compatibility with MROUTING case is now provided in ip_encap.c. fix ipip to work with gif (using ip_encap.c). sorry for breakage. gif now uses ip_encap.c. introduce stf pseudo interface (implements 6to4, another IPv6-over-IPv4 code with ip proto #41).
