30 tristate "CRC-CCITT functions"
32 This option is provided for the case where no in-kernel-tree
33 modules require CRC-CCITT functions, but a module built outside
34 the kernel tree does. Such modules that use library CRC-CCITT
35 functions require M here.
38 tristate "CRC16 functions"
40 This option is provided for the case where no in-kernel-tree
41 modules require CRC16 functions, but a module built outside
42 the kernel tree does. Such modules that use library CRC16
43 functions require M here.
46 tristate "CRC calculation for the T10 Data Integrity Field"
48 This option is only needed if a module that's not in the
49 kernel tree needs to calculate CRC checks for use with the
50 SCSI data integrity subsystem.
53 tristate "CRC ITU-T V.41 functions"
55 This option is provided for the case where no in-kernel-tree
56 modules require CRC ITU-T V.41 functions, but a module built outside
57 the kernel tree does. Such modules that use library CRC ITU-T V.41
58 functions require M here.
61 tristate "CRC32 functions"
65 This option is provided for the case where no in-kernel-tree
66 modules require CRC32 functions, but a module built outside the
67 kernel tree does. Such modules that use library CRC32 functions
71 tristate "CRC7 functions"
73 This option is provided for the case where no in-kernel-tree
74 modules require CRC7 functions, but a module built outside
75 the kernel tree does. Such modules that use library CRC7
76 functions require M here.
79 tristate "CRC32c (Castagnoli, et al) Cyclic Redundancy-Check"
83 This option is provided for the case where no in-kernel-tree
84 modules require CRC32c functions, but a module built outside the
85 kernel tree does. Such modules that use library CRC32c functions
86 require M here. See Castagnoli93.
87 Module will be libcrc32c.
