CRC Functions

crc7 - update the CRC7 for the data buffer
crc16 - compute the CRC-16 for the data buffer
crc_itu_t - Compute the CRC-ITU-T for the data buffer
crc32_le - Calculate bitwise little-endian Ethernet AUTODIN II CRC32
crc32_be - Calculate bitwise big-endian Ethernet AUTODIN II CRC32
crc_ccitt - recompute the CRC for the data buffer
