[PATCH net-next 13/16] net: mscc: ocelot: Handle SWITCHDEV_PORT_ATTR_SET

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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_SET and simply translate that into the existing
ocelot_port_attr_set() call.
