Alexandre Bounine058f88d62010-05-26 14:44:03 -0700[diff] [blame]56 * Manipulating switch route tables and error management in RIO
57 * is switch specific. This registers a switch by vendor and device ID with
58 * initialization callback for setting up switch operations and (if required)
59 * hardware initialization. A &struct rio_switch_ops is initialized with
60 * pointer to the init routine and placed into a RIO-specific kernel section.
