| ISCSI target driver for SCST. The iSCSI protocol has been defined in |
| RFC 3720. To use this target driver you will not only have to enable |
| this kernel module but you will also have to download the |
| corresponding user space daemon from http://scst.sourceforge.net. |

| Simulates iSCSI digest failures in random places. Even when iSCSI |
| traffic is sent over a TCP connection, the 16-bit TCP checksum is too |
| weak for the requirements of a storage protocol. Furthermore, there |
| are also instances where the TCP checksum does not protect iSCSI |
| data, as when data is corrupted while being transferred on a PCI bus |
| or while in memory. The iSCSI protocol therefore defines a 32-bit CRC |
| digest on iSCSI packets in order to detect data corruption on an |
| end-to-end basis. CRCs can be used on iSCSI PDU headers and/or data. |
| Enabling this option allows to test digest failure recovery in the |
| iSCSI initiator that is talking to SCST. |

| If unsure, say "N". |
