Defines
#define	UIP_ND6_OPT_HDR_BUF   ((uip_nd6_opt_hdr *)&uip_buf[uip_l2_l3_icmp_hdr_len + nd6_opt_offset])
	Pointer to ND option.
Pointers to the header structures.
All pointers except UIP_IP_BUF depend on uip_ext_len, which at packet reception, is the total length of the extension headers. The pointer to ND6 options header also depends on nd6_opt_offset, which we set in each function. Care should be taken when manipulating these buffers about the value of these length variables
#define	UIP_IP_BUF   ((struct uip_ip_hdr *)&uip_buf[UIP_LLH_LEN])
	Pointer to IP header.
#define	UIP_ICMP_BUF   ((struct uip_icmp_hdr *)&uip_buf[uip_l2_l3_hdr_len])
	Pointer to ICMP header.
#define	UIP_ND6_RS_BUF   ((uip_nd6_rs *)&uip_buf[uip_l2_l3_icmp_hdr_len])
#define	UIP_ND6_RA_BUF   ((uip_nd6_ra *)&uip_buf[uip_l2_l3_icmp_hdr_len])
#define	UIP_ND6_NS_BUF   ((uip_nd6_ns *)&uip_buf[uip_l2_l3_icmp_hdr_len])
#define	UIP_ND6_NA_BUF   ((uip_nd6_na *)&uip_buf[uip_l2_l3_icmp_hdr_len])
