I found the following in /usr/include/netinet/ip_icmp.h:
struct icmphdr
{
u_int8_t type; /* message type */
u_int8_t code; /* type sub-code */
u_int16_t checksum;
union
{
struct
{
u_int16_t id;
u_int16_t sequence;
} echo; /* echo datagram */
u_int32_t gateway; /* gateway address */
struct
{
u_int16_t __unused;
u_int16_t mtu;
} frag; /* path mtu discovery */
} un;
};
