24 tristate "CRC-CCITT functions"
26 This option is provided for the case where no in-kernel-tree
27 modules require CRC-CCITT functions, but a module built outside
28 the kernel tree does. Such modules that use library CRC-CCITT
29 functions require M here.
32 tristate "CRC16 functions"
34 This option is provided for the case where no in-kernel-tree
35 modules require CRC16 functions, but a module built outside
36 the kernel tree does. Such modules that use library CRC16
37 functions require M here.
40 tristate "CRC calculation for the T10 Data Integrity Field"
42 This option is only needed if a module that's not in the
43 kernel tree needs to calculate CRC checks for use with the
44 SCSI data integrity subsystem.
47 tristate "CRC ITU-T V.41 functions"
49 This option is provided for the case where no in-kernel-tree
50 modules require CRC ITU-T V.41 functions, but a module built outside
51 the kernel tree does. Such modules that use library CRC ITU-T V.41
52 functions require M here.
55 tristate "CRC32 functions"
59 This option is provided for the case where no in-kernel-tree
60 modules require CRC32 functions, but a module built outside the
61 kernel tree does. Such modules that use library CRC32 functions
65 tristate "CRC7 functions"
67 This option is provided for the case where no in-kernel-tree
68 modules require CRC7 functions, but a module built outside
69 the kernel tree does. Such modules that use library CRC7
70 functions require M here.
73 tristate "CRC32c (Castagnoli, et al) Cyclic Redundancy-Check"
77 This option is provided for the case where no in-kernel-tree
78 modules require CRC32c functions, but a module built outside the
79 kernel tree does. Such modules that use library CRC32c functions
80 require M here. See Castagnoli93.
81 Module will be libcrc32c.
