mlxsw: spectrum_switchdev: Handle SWITCHDEV_PORT_ATTR_SET (7464251b) · Commits · 戴 / test

Following patches will change the way we communicate setting a port's attribute and use a notifier to perform those tasks. Prepare mlxsw to support receiving notifier events targeting SWITCHDEV_PORT_ATTR_SET and utilize the switchdev_handle_port_attr_set() to handle stacking of devices. Reviewed-by:
