    iIDMA (Intelligent Interleaved Direct Memory Access) allows for
    the HBA hardware to send FC frames at the rate at which they can
    be received by a target device.  By taking advantage of the
    higher link rate, the HBA can maximize bandwidth utilization in a
    heterogeneous multi-speed SAN.
    Within a fabric topology, port speed detection is done via a Name
    Server command (GFPN_ID) followed by a Fabric Management command
    (GPSC).  In an FCAL/N2N topology, port speed is based on the HBA
