After STEALING Packets (NF_STOLEN); want to send the Manipulated Packet (added extra header) to some of the available net devices. Please let me know what is the Function that I Should call to do this step ?? Also; once the skb was expanded by 20 bytes to add new ip header; do I need to reassign the skb pointer to the new location ?? -Thanks in Advance, VKS -------------- next part -------------- An HTML attachment was scrubbed...
