From 9a1f27c48065ce713eb47f2fd475b717e63ef239 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 7 Oct 2008 11:41:57 -0700 Subject: inet_hashtables: Add inet_lookup_skb helpers To be able to use the cached socket reference in the skb during input processing we add a new set of lookup functions that receive the skb on their argument list.
