In the upstream linuxptp tree, the nullf servo has no way to transition to the SERVO_LOCKED state except when the offset is zero. Transitioning to the SERVO_LOCKED state is important for a servo that makes no frequency adjustments because SERVO_LOCKED_STABLE is the only state that invokes write_phase_mode, a performant way of adjusting the clock offset. The goal of this change is to make it simple to configure entering the SERVO_LOCKED_STABLE state by setting the offset_threshold when using the nullf servo. In cases where the offset_threshold is not set but the step_threshold is, the SERVO_LOCKED state is entered when the offset is within the step_threshold.
