Ping: checks payloads incorrectly, ignores all mismatch replies

Bug description:
= Impact =
the ping statistics are incorrect when dealing with truncated packets
= Test case =
$ ping -c 1 -s 1200 8.8.8.8
should list truncated replies and received packets
= Regression potential =
the changes are limited to the ping source any regression would impact
that utility, check that responses are correctly handled and
statistics reflecting what is expected
