21 tristate "CRC-CCITT functions"
23 This option is provided for the case where no in-kernel-tree
24 modules require CRC-CCITT functions, but a module built outside
25 the kernel tree does. Such modules that use library CRC-CCITT
26 functions require M here.
29 tristate "CRC16 functions"
31 This option is provided for the case where no in-kernel-tree
32 modules require CRC16 functions, but a module built outside
33 the kernel tree does. Such modules that use library CRC16
34 functions require M here.
37 tristate "CRC calculation for the T10 Data Integrity Field"
39 This option is only needed if a module that's not in the
40 kernel tree needs to calculate CRC checks for use with the
41 SCSI data integrity subsystem.
44 tristate "CRC ITU-T V.41 functions"
46 This option is provided for the case where no in-kernel-tree
47 modules require CRC ITU-T V.41 functions, but a module built outside
48 the kernel tree does. Such modules that use library CRC ITU-T V.41
49 functions require M here.
52 tristate "CRC32 functions"
56 This option is provided for the case where no in-kernel-tree
57 modules require CRC32 functions, but a module built outside the
58 kernel tree does. Such modules that use library CRC32 functions
62 tristate "CRC7 functions"
64 This option is provided for the case where no in-kernel-tree
65 modules require CRC7 functions, but a module built outside
66 the kernel tree does. Such modules that use library CRC7
67 functions require M here.
70 tristate "CRC32c (Castagnoli, et al) Cyclic Redundancy-Check"
74 This option is provided for the case where no in-kernel-tree
75 modules require CRC32c functions, but a module built outside the
76 kernel tree does. Such modules that use library CRC32c functions
77 require M here. See Castagnoli93.
78 Module will be libcrc32c.
