From 8e36360ae876995e92d3a7538dda70548e64e685 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 13 May 2011 17:29:41 -0400 Subject: ipv4: Remove route key identity dependencies in ip_rt_get_source(). Pass in the sk_buff so that we can fetch the necessary keys from the packet header when working with input routes. Signed-off-by: David S.
