From def57687e9579b7a797681990dff763c411f5347 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 12 May 2011 19:34:30 -0400 Subject: [PATCH] ipv4: Elide use of rt->rt_dst in ip_forward() No matter what kind of header mangling occurs due to IP options processing, rt->rt_dst will always equal iph->daddr in the packet. So we can safely use iph->daddr instead of rt->rt_dst here. Signed-off-by: David S.
