d_tcp_sack_parse()

int d_tcp_sack_parse	(	const struct rohc_decomp_ctxt *const	context,
		const uint8_t *const	data,
		const size_t	data_len,
		struct d_tcp_opt_sack *const	opt_sack
	)

Parse the SACK TCP option.

See RFC6846 page 68 (and RFC2018 for Selective Acknowledgement option)

Parameters

	context	The decompression context
	data	The ROHC data to parse
	data_len	The length of the ROHC data to parse
[out]	opt_sack	The information of SACK option extracted from the packet

Returns

The number of ROHC bytes parsed, -1 if packet is malformed
