Modify IxNextgen API for traffic model configuration
Changes to IxNextgen API: - modify API for traffic model configuration so that it can be used to create/configure different models - add methods to start and stop protocols on IxNetwork - add method for getting assigned ports JIRA: YARDSTICK-1455 Change-Id: I43c10fea9ba83994caf373ceff8b0252a45439b3 Signed-off-by: Serhiy Pshyk <serhiyx.pshyk@intel.com>
