+# # Stream Type defines ISO OSI network layer

+# # It can be overridden by cli option stream_type.
+# # Values:
+# # "L2" - iteration of destination MAC address
+# # "L3" - iteration of destination IP address
+# # "L4" - iteration of destination port

+# # Default value is "L4".

+# # Values:
+# # "Yes" - flows will be inserted into OVS

+# "Flow Type": ["port"|"IP"] # Optional. Defines flows complexity. In case

+# # Values:
+# # "port" - flow is defined by ingress ports
+# # "IP" - flow is defined by ingress ports
