Fragmented ICMP packets for IPv4 packets.
IPv4 ICMP pings packets with payload size greater than the maximum IPv4 ICMP-allowed size. (The maximum allowed size is configurable.)
IPv6 ICMP ping packets with payload size > the maximum IPv6 ICMP-allowed size. (The maximum allowed size is configurable.)
