uint8_t rohc_add_cid_decode	(	const uint8_t *const	data,
		const size_t	len
	)

Decode the add-CID byte of a ROHC packet (if the add-CID byte is present).

Parameters:

	data	The ROHC packet with a possible add-CID byte
	len	The length of the ROHC packet

Returns:

UINT8_MAX if no add-CID byte is present, the CID value otherwise

static bool rohc_add_cid_is_present	(	const uint8_t *const	data,
		const size_t	len
	)			[static]

Check whether a ROHC packet starts with an add-CID byte or not.

Parameters:

	data	The ROHC packet with a possible add-CID byte
	len	The length of the ROHC packet

Returns:

Whether the ROHC packet starts with an add-CID byte or not
