From 746dc184ba59aa2c843b9e888be3f1302d227b74 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 20 Feb 2019 16:58:19 -0800 Subject: [PATCH 1/8] net: switchdev: Add PORT_PRE_BRIDGE_FLAGS In preparation for removing switchdev_port_attr_get(), introduce PORT_PRE_BRIDGE_FLAGS which will be called through switchdev_port_attr_set(), in the caller's context (possibly atomic) and which must be checked by the switchdev driver in order to return whether the operation is supported or not. This is entirely analoguous to how the BRIDGE_FLAGS_SUPPORT works, except it goes through a set() instead of get().

It's possible, but not optimal, to enable learning on the device port and on the bridge port, and disable learning_sync. To support learning, the driver implements switchdev op -switchdev_port_attr_get/set for SWITCHDEV_ATTR_PORT_ID_BRIDGE_FLAGS. +switchdev_port_attr_set for SWITCHDEV_ATTR_PORT_ID_{PRE}_BRIDGE_FLAGS.
