From 4591db4f37618f37a9f1f25d291c3c7a43a15a21 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Wed, 5 Mar 2008 10:48:10 -0800 Subject: [PATCH] [NETNS][IPV6] route6 - add netns parameter to ip6_route_output Add an netns parameter to ip6_route_output. That will allow to access to the right routing table for outgoing traffic. Signed-off-by: Daniel Lezcano Signed-off-by: Benjamin Thery Signed-off-by: David S.
