[dpdk-dev] [PATCH v3 1/6] ethdev: add devop to check removal status

> There is time between the physical removal of the device until PMDs get
> a RMV interrupt. At this time DPDK PMDs and applications still don't
> know about the removal.
> 
> Current removal detection is achieved only by registration to device RMV
> event and the notification comes asynchronously. So, there is no option
> to detect a device removal synchronously.
> Applications and other DPDK entities may want to check a device removal
> synchronously and to take an immediate decision accordingly.
> 
> Add new dev op called is_removed to allow DPDK entities to check an
> Ethernet device removal status immediately.
