+    This test is meant to verify the forwarding of the default traffic
+    when the rule for the PW transport (BoS=0) has been installed in the
+    switch, together with the rule for the transport of default routing
+    traffic. There is a bug in OFDPA 3.0EA4, which requires BOS=0 flow
+    to be installed before BOS=1 flow to generate correct packets. Incoming
+    packet has 1 label, and there is no VLAN tag in the incoming packet.
+    The expected behvior is the Pop of the outer MPLS label and plain IP
+    packet should exit from the switch.
