spdk_crc16_t10dif()

uint16_t spdk_crc16_t10dif	(	uint16_t	init_crc,
		const void *	buf,
		size_t	len
	)

Calculate T10-DIF CRC-16 checksum.

Parameters

init_crc	Initial CRC-16 value.
buf	Data buffer to checksum.
len	Length of buf in bytes.

Returns

CRC-16 value.

spdk_crc16_t10dif_copy()

uint16_t spdk_crc16_t10dif_copy	(	uint16_t	init_crc,
		uint8_t *	dst,
		uint8_t *	src,
		size_t	len
	)

Calculate T10-DIF CRC-16 checksum and copy data.

Parameters

init_crc	Initial CRC-16 value.
dst	Destination data buffer for copy.
src	Source data buffer for CRC calculation and copy.
len	Length of buffer in bytes.

Returns

CRC-16 value.
