Subject: [PATCH net-next V6 4/6] net: add support for sending RFC 8335 PROBE messages

Modify the ping_supported function to support PROBE message types. This
allows tools such as the ping command in the iputils package to be
modified to send PROBE requests through the existing framework for
sending ping requests.
