Subject: [PATCH net-next 10/16] rocker: 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 rocker to support receiving notifier events targeting
SWITCHDEV_PORT_ATTR_SET and simply translate that into the existing
rocker_port_attr_set call.
