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