The devices must be allocated at a low level layer.
When a new device appears (hotplug), an ethdev port should be allocated
automatically if it passes the whitelist/blacklist policy test.
Then we must decide who will manage this device.
I suggest notifying the DPDK libs first.
So a DPDK lib or PMD like failsafe can have the priority to take the
ownership in its notification callback.
