 *       Filename:  genericTracePktGen.h
 *
 *    Description: Used to inject traces from a cycle accurate simulator into
 *    iris as network traffic.
 *    Does have some additional queues for mshr modelling which a genericTPG
 *    does not need. TODO: Remove mshr modelling.
 *
 *        Version:  1.0
