Improve IXIA IxNetwork library and traffic profile (2)
This patch modifies the way the packet frame and the flow is configured before the injection. "IxNextgen.update_frame" modifies the L2 frame according to the test case and setup the frame rate, frame size, traffic injection duration and MAC addresses.
