Use testpmd for example, to show how an application uses device event APIs to monitor the hotplug events, including both hot removal event and hot insertion event. The process is that, testpmd first enable hotplug by below commands, E.g. ./build/app/testpmd -c 0x3 --n 4 -- -i --hot-plug then testpmd starts the device event monitor by calling the new API (rte_dev_event_monitor_start) and register the user's callback by call the API (rte_dev_event_callback_register), when device being hotplug insertion or hotplug removal, the device event monitor detects the event and call user's callbacks, user could process the event in the callback accordingly. This patch only shows the event monitoring, device attach/detach would not be involved here, will add from other hotplug patch set.
