61 * is switch specific. This registers a switch by vendor and device ID with
62 * initialization callback for setting up switch operations and (if required)
63 * hardware initialization. A &struct rio_switch_ops is initialized with
64 * pointer to the init routine and placed into a RIO-specific kernel section.
