The BGX interface is unconnected in the ThunderX units in the netperf cluster

You mean network interfaces are not connected to anything?
This is not a problem as we need to know whether BGX attaches & configures PHYs. Even if the network is not connected we can still bring-up VFs using iovctl.

@andrew Do you have any objections to committing this patch? If not, I would like to push it to head. It was marinated long enough here :)
