Kernel v6.15+ removed LIBCRC32C and switched in-tree users to CRC32. Keep older kernels working by accepting either CRC32 or LIBCRC32C in Kconfig and preprocessor guards, so crc32c() usage compiles and links on both old and new kernels.

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".
