This is a follow-up of an idea presented at Dublin during the "hotplug talk".
The idea is to ease probing of range of ports attached to the same rte_device. I becomes possible to allow probing again the same device but with a bigger range of ports in the devargs. Instead of adding a parameter to the hotplug functions, as in the RFC, the check of an already probed device is moved to the bus and enabled PMDs. It gives flexibility to drivers for managing range of ports.
