Well, keep in mind that this driver is for an ethernet virtual NIC
that is actually
remote across another network (an InfiniBand fabric) -- so these devices
can actually appear or disappear at random times by their nature.  It's a
similar issue to, say, a USB ethernet adapter presents -- there's no sane way
to have operstate set for a device that hasn't been attached yet.
