In an FL topology, limit port recognition to those devices
not within the same area and domain of the ISP.  The
firmware will recogonize such devices during local-loop
discovery.

Some devices may respond to a PLOGI before they have
completed their fabric login or they may not be a public
device. In this case they will report:

        domain == 00
        area == 00
        alpa == <XX>

which is valid. Exclude such devices from local loop
discovery.
