The StorPortNvmeIceIoStart function initiates an NVMe ICE (Inline Cryptographic Engine) I/O operation.
HwDeviceExtension[in] A pointer to the hardware device extension. This is a per HBA (Host Bus Adapter) context area provided by the miniport driver. The miniport driver can store HBA-specific information here.
Srb[in] A pointer to a SCSI request block. This structure represents a single I/O request.
LbaCount[in] The number of logical block addresses (LBAs) to be transferred.
PrpCount[in] The number of physical region pages (PRPs) to be transferred.
Prp1[in/out] A pointer to the first PRP, used in NVMe to describe the physical memory locations involved in the data transfer.
Prp2[in/out] A pointer to the second PRP, used in NVMe to describe the physical memory locations involved in the data transfer.
PrpList[in/out] A pointer to a list of additional PRPs.
