From 3a7fda06ba48e97650fe44ea8e8a7cc385e1c100 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 29 Jul 2010 00:45:30 +0000 Subject: [PATCH] bridge: Allow multicast snooping to be disabled before ifup Currently you cannot disable multicast snooping while a device is down. There is no good reason for this restriction and this patch removes it. Signed-off-by: Herbert Xu Signed-off-by: David S.
