-// ListenPacket listens for incoming ICMP packets addressed to
-// address. See net.Dial for the syntax of address.
-//
-// For non-privileged datagram-oriented ICMP endpoints, network must
-// be "udp4" or "udp6". The endpoint allows to read, write a few
-// limited ICMP messages such as echo request and echo reply.
-// Currently only Darwin and Linux support this.
-//
-// Examples:
-// ListenPacket("udp4", "192.168.0.1")
-// ListenPacket("udp4", "0.0.0.0")
-// ListenPacket("udp6", "fe80::1%en0")
-// ListenPacket("udp6", "::")
-//
-// For privileged raw ICMP endpoints, network must be "ip4" or "ip6"
-// followed by a colon and an ICMP protocol number or name.
-//
-// Examples:
-// ListenPacket("ip4:icmp", "192.168.0.1")
-// ListenPacket("ip4:1", "0.0.0.0")
-// ListenPacket("ip6:ipv6-icmp", "fe80::1%en0")
