From 7464251b15d98e31f0c0aec2f883db979d15f9f1 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 27 Feb 2019 11:44:28 -0800 Subject: [PATCH] mlxsw: spectrum_switchdev: Handle SWITCHDEV_PORT_ATTR_SET Following patches will change the way we communicate setting a port's attribute and use a notifier to perform those tasks. Prepare mlxsw to support receiving notifier events targeting SWITCHDEV_PORT_ATTR_SET and utilize the switchdev_handle_port_attr_set() to handle stacking of devices.
