This is a writable action object that lets a management station command the device to clear (reset) the accumulated counters in this QoS shaper's current statistics bin. It matters because after investigating a shaping problem an admin may want to zero out the counters so subsequent readings reflect only new activity, rather than manually tracking a baseline offset. For example, after resolving a burst of tail-dropped frames on a shaper, an admin would write to cmQosShaperStatsAction to clear the bin so the next 5-minute reading starts from zero.
