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
