Hi I am writing some netfilter kernel module for my OpenWRT Backfire rev 
28680 build for Dir-300(AR23xx).

I have written some hook_function but unfortunatly any sk_buff i get in 
it is corrupted. There is only trash in it and as a
Could some of u tell me what am i doing wrong? The skb_network_header 
function always returns NULL.

I have included example of my code.

I would be extremely grateful for any sort of help.

Regards

Dawid
