Subject[PATCH net-next 12/16] mlxsw: spectrum_switchdev: 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 mlxsw to support receiving notifier events targeting
SWITCHDEV_PORT_ATTR_SET and simply translate that into the existing
mlxsw_sp_port_attr_set() call.
