Macros
#define	L2UTIL_ADDR_MAX_LEN (8U)
	maximum expected length for addresses

Functions
int	l2util_eui64_from_addr (int dev_type, const uint8_t addr, size_t addr_len, eui64_t eui64)
	Converts a given hardware address to an EUI-64.

int	l2util_ipv6_iid_from_addr (int dev_type, const uint8_t addr, size_t addr_len, eui64_t iid)
	Converts a given hardware address to an IPv6 IID.

int	l2util_ipv6_iid_to_addr (int dev_type, const eui64_t iid, uint8_t addr)
	Converts an IPv6 IID to a hardware address.

int	l2util_ndp_addr_len_from_l2ao (int dev_type, const ndp_opt_t *opt)
	Derives the length of the link-layer address in an NDP link-layer address option from that option's length field and the given device type.

int	l2util_ipv6_group_to_l2_group (int dev_type, const ipv6_addr_t ipv6_group, uint8_t l2_group)
	Converts an IPv6 multicast address to a multicast address of the respective link layer.

char *	l2util_addr_to_str (const uint8_t addr, size_t addr_len, char out)
	Converts a hardware address to a human readable string.

size_t	l2util_addr_from_str (const char str, uint8_t out)
	Parses a string of colon-separated hexadecimals to a hardware address.

static bool	l2util_addr_equal (const uint8_t addr_a, uint8_t addr_a_len, const uint8_t addr_b, uint8_t addr_b_len)
	Checks if two l2 addresses are equal.
