Subject: [PATCH net-next v2 14/16] staging: fsl-dpaa2: ethsw: Handle SWITCHDEV_PORT_ATTR_SET

Following patches will change the way we communicate getting or setting
a port's attribute and use a blocking notifier to perform those tasks.

Prepare ethsw to support receiving notifier events targeting
SWITCHDEV_PORT_ATTR_SET and simply translate that into the existing
swdev_port_attr_set() call.
