As we may know, we have eal event for rte device hotplug and ethdev event for ethdev hotplug. Some ethdev need to use eal event to detect hotplug behaviors, the privors way is register eal event callback in app, but seems that it will have some race between these 2 event process. In oder to fix the problem, it might be better to find a way to combind these 2 events detect.
This patch set introduce a way to combind these 2 event, by register the eal event callback in pmd driver and trigger the ethdev hotplug event in the callback. That will let the ethdev device can easy process hotplug by a common way. Here let i40 pmd driver for example, other driver which support hotplug feature could be use this way to enable hotplug.
