This patch aim to enable hotplug detect in ixgbe pmd driver. Firstly it
set the flags RTE_PCI_DRV_INTR_RMV in drv_flags to announce the hotplug
ability, and then use rte_dev_event_callback_register to register
the hotplug event callback to eal. When eal detect the hotplug event,
it will call the callback to process it, if the event is hotplug remove,
it will trigger the RTE_ETH_EVENT_INTR_RMV event into ethdev callback
to let app process the hotplug for the ethdev.
This is an example for other driver, that if any driver support hotplug
feature could be use this way to enable hotplug detect.
I see nothing ixgbe specific in the callback. Yes, support of removal
event should be in drv_flags, but it looks like the callback may be
generic and located in ethdev.
Also search of the device by name could be done using querying
mechanism to be added by Gaetan [1].
