+ ISCSI target driver for SCST framework. The iSCSI protocol has been
+ defined in RFC 3720. To use it you should download from
+ http://scst.sourceforge.net the user space part of it.

+config SCST_ISCSI_DEBUG_DIGEST_FAILURES
+ bool "Simulate iSCSI digest failures"
+ depends on SCST_ISCSI
+ help
+ 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".
