There is time between the physical removal of the device until sub-device PMDs get a RMV interrupt. At this time DPDK PMDs and applications still don't know about the removal and may call sub-device control operation which should return an error.
This series adds new ethdev operation to check device removal, adds support for it in mlx PMDs and fixes the fail-safe bug of removal error report. V2: Remove ENODEV definition. Remove checks from all mlx control commands. Add new devop - "is_removed". Implement it in mlx4 and mlx5. Fix failsafe bug by the new devop.
