From 045a5a99141d96e6254664783e8afb4e298ae2c9 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Wed, 17 Oct 2018 08:53:27 +0000 Subject: [PATCH] vxlan: Notify for each remote of a removed FDB entry When notifications are sent about FDB activity, and an FDB entry with several remotes is removed, the notification is sent only for the first destination. That makes it impossible to distinguish between the case where only this first remote is removed, and the one where the FDB entry is removed as a whole. Therefore send one notification for each remote of a removed FDB entry. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S.
