29# Test ip:::{send,receive} of IPv4 ICMP to a remote host.
30#
31# This may fail due to:
32#
33# 1. A change to the ip stack breaking expected probe behavior,
34#    which is the reason we are testing.
35# 2. No physical network interface is plumbed and up.
36# 3. No other hosts on this subnet are reachable.
37# 4. An unrelated ICMP between these hosts was traced by accident.
