From f3db48517f59133610f558f29de8834d7b007691 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Mon, 3 Mar 2008 23:27:06 -0800 Subject: [NETNS][IPV6] ip6_fib - fib6_clean_all handle several network namespaces The function fib6_clean_all takes the network namespace as parameter. That allows to flush the routes related to a specific network namespace. Signed-off-by: Daniel Lezcano Signed-off-by: Benjamin Thery Signed-off-by: David S.
