The scsi-options property is an integer specifying a number of options through individually defined bits. The bits in scsi_options are:
SCSI_OPTIONS_DR (0x008) - If not set, the HBA should not grant disconnect privileges to a target device.
SCSI_OPTIONS_LINK (0x010) - If not set, the HBA should not enable linked commands.
SCSI_OPTIONS_SYNC (0x020) - If not set, the HBA should not negotiate synchronous data transfer, and should reject any attempt to negotiate synchronous data transfer initiated by a target.
SCSI_OPTIONS_PARITY (0x040) - If not set, the HBA should run the SCSI bus without parity.
SCSI_OPTIONS_TAG (0x080) - If not set, the HBA should not operate in Command Tagged Queuing mode.
SCSI_OPTIONS_FAST (0x100) - If not set, the HBA should not operate the bus in FAST SCSI mode.
SCSI_OPTIONS_WIDE (0x200) - If not set, the HBA should not operate the bus in WIDE SCSI mode.
