28# Test {udp,ip}:::{send,receive} of IPv4 UDP to a remote host.
29#
30# This may fail due to:
31#
32# 1. A change to the ip stack breaking expected probe behavior,
33#    which is the reason we are testing.
34# 2. No physical network interface is plumbed and up.
35# 3. No other hosts on this subnet are reachable and listening on rpcbind.
36# 4. An unlikely race causes the unlocked global send/receive
37#    variables to be corrupted.
38#
39# This test sends a UDP message using perl and checks that at least the
40# following counts were traced:
41#
42# 1 x ip:::send (UDP sent to ping's base UDP port)
43# 1 x udp:::send (UDP sent to ping's base UDP port)
