[dpdk-dev,03/12] ethdev: add deferred intermediate device state
Checks
Commit Message
This device state means that the device is managed externally, by
whichever party has set this state (PMD or application).
Note: this new device state is only an information. The related device
structure and operators are still valid and can be used normally.
It is however made private by device management helpers within ethdev,
making the device invisible to applications.

Might be better to introduce RFC2863 operational states.
This is something management tools might want.
