33 tristate "CRC-CCITT functions"
35 This option is provided for the case where no in-kernel-tree
36 modules require CRC-CCITT functions, but a module built outside
37 the kernel tree does. Such modules that use library CRC-CCITT
38 functions require M here.
41 tristate "CRC16 functions"
43 This option is provided for the case where no in-kernel-tree
44 modules require CRC16 functions, but a module built outside
45 the kernel tree does. Such modules that use library CRC16
46 functions require M here.
49 tristate "CRC calculation for the T10 Data Integrity Field"
51 This option is only needed if a module that's not in the
52 kernel tree needs to calculate CRC checks for use with the
53 SCSI data integrity subsystem.
56 tristate "CRC ITU-T V.41 functions"
58 This option is provided for the case where no in-kernel-tree
59 modules require CRC ITU-T V.41 functions, but a module built outside
60 the kernel tree does. Such modules that use library CRC ITU-T V.41
61 functions require M here.
64 tristate "CRC32 functions"
68 This option is provided for the case where no in-kernel-tree
69 modules require CRC32 functions, but a module built outside the
70 kernel tree does. Such modules that use library CRC32 functions
74 tristate "CRC7 functions"
76 This option is provided for the case where no in-kernel-tree
77 modules require CRC7 functions, but a module built outside
78 the kernel tree does. Such modules that use library CRC7
79 functions require M here.
82 tristate "CRC32c (Castagnoli, et al) Cyclic Redundancy-Check"
86 This option is provided for the case where no in-kernel-tree
87 modules require CRC32c functions, but a module built outside the
88 kernel tree does. Such modules that use library CRC32c functions
89 require M here. See Castagnoli93.
