Improve IXIA IxNetwork library and traffic profile (4)
This patch implements an active wait for the traffic injection. Once the traffic is started, the traffic generator class will poll periodically the IXIA traffic generator chassis to retrieve the status of the traffic ("started", "stopped"). Now the latency statistics are retrieved and reported for each injection period.
