We kept it keeping in mind for future use, specially for switchdev API
and OVS support. But for this patch it is not necessary to be here. We
will remove it from here now. New patch will be submitted if needed in

Thanks Ferruh. We will also remove this flag option. Without this flag
option, we can still identify the PMD as a port representor type or not
by looking at the device name.
