This gauge reports how far along, typically as a percentage, the FSM workflow tracked by the finite-state-machine object that drives a physical port's own workflow (such as a re-discovery cycle) from start to finish has advanced. An administrator waiting on a discovery or reconfiguration operation polls progress on this PhysFsm instance to distinguish steady advancement from a stall. For example, a progress value frozen at the same number across several successive polls of this PhysFsm instance suggests the workflow needs manual intervention.
