Subject: [PATCH net-next v4 6/9] staging: fsl-dpaa2: ethsw: Handle SWITCHDEV_PORT_ATTR_GET/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_GET/SET and simply translate that into the existing
swdev_port_attr_{set,get} calls.
