I have created a very simple module to use netfilters. I display some info from the sk_buff structures. The protocol field always has an 8 in it.
What does the 8 mean? I would expect this to indicate this is an IP packet of some type, but so far I have not found a header or any docs that explains it. Where would be a good place for me to find these things out (please don't say read the kernel source).
Thanks,
Ken
