This patch aims to add a general device event monitor framework at EAL device layer, for device hotplug awareness and actions adopted accordingly. It could also expand for all other types of device event monitor, but not in this scope at the stage. To get started, users firstly call below new added APIs to enable/disable the device event monitor mechanism: - rte_dev_event_monitor_start - rte_dev_event_monitor_stop Then users shell register or unregister callbacks through the new added APIs. Callbacks can be some device specific, or for all devices. -rte_dev_event_callback_register -rte_dev_event_callback_unregister Use hotplug case for example, when device hotplug insertion or hotplug removal, we will get notified from kernel, then call user's callbacks accordingly to handle it, such as detach or attach the device from the bus, and could benefit further fail-safe or live-migration.
