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
