__wsum csum_partial	(	const void *	buff,
		int	len,
		__wsum	sum
	)

csum_partial - Compute an internet checksum. : buffer to be checksummed : length of buffer. : initial sum to be added in (32bit unfolded)

Returns the 32bit unfolded internet checksum of the buffer. Before filling it in it needs to be csum_fold()'ed. buff should be aligned to a 64bit boundary if possible.
