From a4e6db07984529847c6ad8bc616485e721dcb809 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 27 Jan 2009 22:41:03 -0800 Subject: ipv6: Make mc_forwarding sysctl read-only. The kernel manages this value internally, as necessary, as VIFs are added/removed and as multicast routers are registered and deregistered. Signed-off-by: David S.
