[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. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
