[SCSI] qla2xxx: Add iIDMA support.
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
link-rate.
