Subject[PATCH net-next v2 11/16] net: dsa: Handle SWITCHDEV_PORT_ATTR_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 DSA to support receiving notifier events targeting
SWITCHDEV_PORT_ATTR_SET and simply translate that into the existing
dsa_slave_port_attr_set() call.
