Subject[RFC net-next 05/13] net: mscc: ocelot: Handle SWITCHDEV_PORT_ATTR_GET/SET
Date
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 ocelot to support receiving notifier events targeting
SWITCHDEV_PORT_ATTR_GET/SET and simply translate that into the existing
ocelot_port_attr_{set,get} calls.
