From d8b4521349274ab610d0b29384c704444e55cbca Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Mon, 2 Oct 2006 12:00:43 -0700 Subject: [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.
