35  * The VSCSI client builds a SCSI Remote Protocol (SRP) Information Unit
38  * payload of a CRQ message.  The server DMAs the SRP IU and processes it,
40  * DMAs the SRP response back to the same address as the request came from,
580  * @format:     SRP or MAD format
601  * set_srp_direction: Set the fields in the srp related to data

746  * map_data_for_srp_cmd: - Calls functions to map data for srp cmds
751  * Called by scsi_cmd_to_srp_cmd() when converting scsi cmds to srp cmds
