From 816a3bed9549fcc0c90ba97c9077e64e734f0df6 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 3 May 2018 14:43:46 +0200 Subject: switchdev: Add fdb.added_by_user to switchdev notifications The following patch enables sending notifications also for events on FDB entries that weren't added by the user. Give the drivers the information necessary to distinguish between the two origins of FDB entries. To maintain the current behavior, have switchdev-implementing drivers bail out on notifications about non-user-added FDB entries. In case of mlxsw driver, allow a call to mlxsw_sp_span_respin() so that SPAN over bridge catches up with the changed FDB.
