    Subject[PATCH net-next 4/8] mlxsw: spectrum_switchdev: Handle SWITCHDEV_PORT_ATTR_SET
    Date
    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.
