Andreas Roeseler d329ea5bd8 icmp: add response to RFC 8335 PROBE messages ... Modify the icmp_rcv function to check PROBE messages and call icmp_echo if a PROBE request is detected. Modify the existing icmp_echo function to respond ot both ping and PROBE requests. This was tested using a custom modification to the iputils package and wireshark. It supports IPV4 probing by name, ifindex, and probing by both IPV4 and IPV6 addresses. It currently does not support responding to probes off the proxy node (see RFC 8335 Section 2). The modification to the iputils package is still in development and can be found here: https://github.com/Juniper-Clinic-2020/iputils.git. It supports full sending functionality of PROBE requests, but currently does not parse the response messages, which is why Wireshark is required to verify the sent and recieved PROBE messages. The modification adds the ``-e'' flag to the command which allows the user to specify the interface identifier to query the probed host. An example usage would be <./ping -4 -e 1 [destination]> to send a PROBE request of ifindex 1 to the destination node.
