From 38f507f1ba013effec3d7deb84273ac1829e6b87 Mon Sep 17 00:00:00 2001 From: WANG Cong Date: Thu, 1 Sep 2016 21:53:44 -0700 Subject: [PATCH] vxlan: call peernet2id() in fdb notification netns id should be already allocated each time we change netns, that is, in dev_change_net_namespace() (more precisely in rtnl_fill_ifinfo()). It is safe to just call peernet2id() here. Cc: Nicolas Dichtel Signed-off-by: Cong Wang Acked-by: Nicolas Dichtel Signed-off-by: David S.
