From 61d57f87f3fb04a305f22befabd042ffbec8b852 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 24 Jan 2012 18:23:30 -0500 Subject: [PATCH] ip_gre: Fix bug added to ipgre_tunnel_xmit(). We can remove the rt_gateway == 0 check but we shouldn't remove the 'dst' initialization too. Noticed by Eric Dumazet. Signed-off-by: David S.
