The GIF man page suggests that the GIF tunnelling behaviour is based on RFC1933, which outlines transition mechanisms for IPv6 (basically v6 in v4 tunnelling). So far as v6-in-v6 and v4-in-v6 tunnelling is concerned, does GIF implement RFC2473 (Generic Packet Tunnelling in IPv6)? Also, does the GIF driver perform packet encapsulation itself, or does it pass inner packets through the stack for encapsulation in the outer packet? (I'm wondering about v6 extension headers in the outer packet). Any help gratefully received. Thanks in advance.
