The popular utility ping has several severe limitations such as the inability to query specific interfaces on a node and requiring bidirectional connectivity between the probing and the probed interfaces. RFC8335 attempts to solve these limitations by creating the new utility PROBE which is a specialized ICMP message that makes use of the ICMP Extension Structure outlined in RFC4884.
This patchset adds definitions for the ICMP Extended Echo Request and Reply (PROBE) types for both IPv4 and IPv6. It also expands the list of supported ICMP messages to accommodate PROBEs.
