            Bug ID: 212454
           Summary: iSCSI hardware CRC32C support
           Product: Base System
           Version: 11.0-STABLE
          Hardware: Any
                OS: Any

Hello,

HeaderDigest and DataDigest are useful options for data integrity.
They are based on CRC32C.
Intel CPUs support iSCSI hardware CRC32C through SSE 4.2.

It would then really be nice to have hardware CRC32C supported on both
initiator and target sides.

Thank you very much !

Best regards,

Ben
