> This patch aim to enable hotplug detect in i40e PMD. Firstly it set the flags
> RTE_PCI_DRV_INTR_RMV in drv_flags to announce the hotplug ability, and
> then use rte_eth_dev_event_handler_install to install the hotplug event
> handler for ethdev. When eal detect the hotplug event, it will call the ethdev
> callback to process it. If the event is hotplug removal, it will trigger the
> RTE_ETH_EVENT_INTR_RMV event into ethdev callback to let app process the
> hotplug for this ethdev.
> 
> This is an example for other driver, that if any driver support hotplug feature
> could be use this way to install hotplug handler.
