The Target interface allows the LSIFC929 to be used as the system
interface for FC bridge controllers. The LSIFC929 provides an FCP
exchange level message interface that routes commands to the system.
The system identifies the appropriate data, and passes a Scatter Gather
List (SGL) to the LSIFC929 describing the data to transfer. A single
Target message directs the LSIFC929 to send a Xfer_Rdy, as needed,
and to transfer data and FCP response. Target specific Process
Login/Logout is managed by the system. For more information regarding
the Target Message Class, refer to the LSI Logic Fusion-MPT
specification.
