[Meaning] Reports the unit-control operations implemented by the miniport driver. The Storport driver calls HwStorUnitControl with this control type after the HBA has been initialized but before the first I/O. The miniport driver fills in the SCSI_SUPPORTED_CONTROL_TYPE_LIST structure at Parameters with the operations it supports. After HwStorUnitControl returns from this call, the Storport driver calls the miniport driver's HwStorUnitControl only for supported operations. [IRQL] PASSIVE_LEVEL [Spinlock] None [Control Type]
