Detailed Description

Handle encoding of TCP TimeStamp (TS) option.

bool c_tcp_ts_lsb_code	(	const struct rohc_comp_ctxt *const	context,
		const uint32_t	timestamp,
		const size_t	nr_bits_minus_1,
		const size_t	nr_bits_0x40000,
		const size_t	nr_bits_0x4000000,
		uint8_t *const	rohc_data,
		const size_t	rohc_max_len,
		size_t *const	rohc_len
	)

Compress the TimeStamp option value.

See RFC4996 page 65

Parameters:

	context	The compression context
	timestamp	The timestamp value to compress
	nr_bits_minus_1	The minimal number of required bits for p = -1
	nr_bits_0x40000	The minimal number of required bits for p = 0x40000
	nr_bits_0x4000000	The minimal number of required bits for p = 0x4000000
`[out]`	rohc_data	The ROHC packet being built
	rohc_max_len	The max remaining length in the ROHC buffer
`[out]`	rohc_len	The length appended in the ROHC buffer
