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

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. More...

int	l2util_ipv6_group_to_l2_group (int dev_type, const ipv6_addr_t ipv6_group, uint8_t l2_group)
