The scsi-options property is an integer specifying a number of options through individually defined bits:
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 driver must not negotiate synchronous data transfer. The driver 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.
