Improve IXIA IxNetwork library and traffic profile (1)
This patch introduces a new way to configure the TCL IxNetwork server. All the configuration is done using the TCL API, removing the need of using the pre-saved configuration file. "IxNextgen.assign_ports" creates and assigns the virtual ports for each physical port defined in the test case. "IxNextgen.create_traffic_item" creates one traffic item and two flow groups per pair of ports, in both directions. "IxNextgen.gt_statistics" retrieves only the required statistics to generate the samples blob in the traffic generator.
