Hi,
I'm trying to understand the sit driver code net/ipv6/sit.c
(2.6.35.12). I'm trying to forward incoming packet from another
interface (eth0) to ISATAP tunnel interface (is0) by calling
dev_queue_xmit (dev) with dev set to is0. Eventually ipip6_tunnel_xmit
routine is getting called, skb_dst()->neighbor is returning null. (I
think this is returning null since the dest ip(v6) is incorrectly
set). I would like to know what should be the header fields that needs
to be set when passing down to tunnel, in order to forward it to
isatap router. Please let me know
