Dear all, I forgot to mention that in status.c everything works fine when I do: struct iphdr * network_header; network_header = (struct iphdr *)skb_network_header(skb); if (network_header->protocol==IPPROTO_TCP){ ... } the problem is how to correctly set the network header pointer in the skb in rx.c Please, can somebody help?
