Detailed Description

Cyclic redundancy checks.

Function Documentation

u16 crc16_ccitt	(	const u8 *	buf,
		u32	len,
		u16	crc
	)

Calculate CCITT 16-bit Cyclical Redundancy Check (CRC16).

This implementation uses parameters used by XMODEM i.e. polynomial is:

\[ x^{16} + x^{12} + x^5 + 1 \]

Mask 0x11021, not reversed, not XOR'd (there are several slight variants on the CCITT CRC-16).

Parameters

buf	Array of data to calculate CRC for
len	Length of data array
crc	Initial CRC value

Returns

CRC16 value
