      Description

      Each NetFlow v9 packet includes the template for the data records. Never seen that before. Furthermore it looks like flowStartMilliseconds (152) and flowEndMilliseconds (153) is used for indicating the start / end of the flow. I'm pretty sure we use FIRST_SWITCHED (22) and LAST_SWITCHED (21) for this. Also each flow seems to have a duration of zero which is also strange.
