- Why I did it * To support systems with dynamic port configuration * Apply lazy initialization to faster the speed of loading platform API - How I did it * Add module.py to implement dynamic port configuration (aka line card model) * Adjust chassis.py, platform.py, thermal.py, sfp.py to support dynamic port configuration * Optimize existing code - How to verify it Platform regression on MSN4700, MSN3800 and MSN2700, 100% pass Unit test covers all new changes.
