(usagi-users 01406) help required with kernel nat-pt (linux)

[Ravi Samprathi <rsamprat@xxxxxxxxx>]

Hi
I have one question regarding the nat-pt.
My question is as follows:
I capture an IPV4 packet by registering at the netfilter
pre-routing hook, i translate it to an IPV6 packet and
allocate a newskb for the translated packet.
Now, I want to put the new-ipv6-packet in the IPV6 stack.
How do i do this?  How can i put the IPV6 packet
in the IPV6 stack?  And also, in the other case, where
i receive an IPV6 packet and translate it to IPV4 packet,
how do i put it on the IPV4 stack?

The flow is as follows:
---At the ipv4 prerouting hook----
receive skb(ipv4)             - Done
translate skb to newskb(ipv6) - Done
put newskb on ipv6 stack      - How ?????
drop original skb             - Done

----At the ipv6 prerouting hook-----
receive skb(ipv6)             - Done
translate skb to newskb(ipv4) - Done
put newskb on ipv4 stack      - How ?????
drop original skb             - Done


I used netif_rx(newskb), but this doesnt seem to be
working.
Please help me.
I greatly appreciate any pointers/feedback/help.
I am hoping you will help me with this.
Thanks very much.
Have a good day.
Best regards.
Ravi
