From 78fbfd8a653ca972afe479517a40661bfff6d8c3 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sat, 12 Mar 2011 00:00:52 -0500 Subject: ipv4: Create and use route lookup helpers. The idea here is this minimizes the number of places one has to edit in order to make changes to how flows are defined and used. Signed-off-by: David S.
