From c19c44f867ca3c0bb3b820c9234590dbd0f7afbe Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 20 Feb 2019 16:58:20 -0800 Subject: [PATCH] mlxsw: spectrum: Handle PORT_PRE_BRIDGE_FLAGS In preparation for getting rid of switchdev_port_attr_get(), have mlxsw check for the bridge flags being set through switchdev_port_attr_set() when the SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS attribute identifier is used.
