My understanding is that the pre routing hook gets the fragmented packet , which is later in defragged in local in in the ip_local_input funx. ie If I print the skb in pre route hook, I shall get the individual frags, whereas in local in hook I would get the complete packet. Is this absolutely correct ? Am I gettting the right picture or is there anything else that I should know? I would be grateful if someone could clear my doubt. Sincerely, Devesh Agrawal
