+ help
+ This option is only needed if a module that's not in the
+ kernel tree needs to calculate CRC checks for use with the
+ SCSI data integrity subsystem.

+config CRC_ITU_T
+ tristate "CRC ITU-T V.41 functions"
+ help
+ This option is provided for the case where no in-kernel-tree
+ modules require CRC ITU-T V.41 functions, but a module built outside
+ the kernel tree does. Such modules that use library CRC ITU-T V.41
+ functions require M here.
