From 584d73df06253f206e31ff897a475283167bf0f0 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Wed, 24 Aug 2016 12:00:26 +0200 Subject: [PATCH] mlxsw: spectrum: Configure learning for VLAN-aware bridge port We are going to prevent the device from generating learning notifications for a port that was configured with learning disabled. Since learning configuration is done per {Port, VID} we need to apply the port's learning configuration for any VID that is added to the bridge port's VLAN filter list. When a VID is added to the VLAN filter list of a VLAN-aware bridge port, configure the {Port, VID} learning status according to the port's configuration. When the VID is removed, disable learning for the {Port, VID}. Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S.
