Sorry, I received those mails in reversed order.

Ah, I noticed that gif routines need to be defiend in protosw,
and they are defined like below with "#ifdef NGIF" directive.

in netinet/in_gif.c
  #if NGIF > 0
  { SOCK_RAW,     &inet6domain,   IPPROTO_IPV4,   PR_ATOMIC|PR_ADDR,
    in6_gif_input,0,              0,              0,
    0,    
    0,            0,              0,              0,
    &nousrreqs
  },
  { SOCK_RAW,     &inet6domain,   IPPROTO_IPV6,   PR_ATOMIC|PR_ADDR,
    in6_gif_input,0,              0,              0,
    0,
    0,            0,              0,              0,
    &nousrreqs
  },
  #endif /* GIF */


in netinet6/in_gif.c
  #if NGIF > 0
  { SOCK_RAW,     &inet6domain,   IPPROTO_IPV4,   PR_ATOMIC|PR_ADDR,
    in6_gif_input,0,              0,              0,
    0,    
    0,            0,              0,              0,
    &nousrreqs
  },
  { SOCK_RAW,     &inet6domain,   IPPROTO_IPV6,   PR_ATOMIC|PR_ADDR,
    in6_gif_input,0,              0,              0,
    0,
    0,            0,              0,              0,
    &nousrreqs
  },
  #endif /* GIF */


Some consideration like in ip_mroute.c might be necessary.
