  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 ping 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)
