New periodic calibration scheme needed for 11n parts that have
multiple algorithms and potentially collect multiple samples. Instead of a single calibration interval we now have short and long intervals; the long interval roughly corresponds to the previous single interval. The short interval is used to speedup collection of samples and happens much quicker. We make calls using the short interval until we're told the calibration work is complete at which point we fallback to the long interval. In addition there is a much longer reset interval used to flush all calibration state and cause everthing to start anew. With these changes you can also disable calibration entirely by setting the long interval to zero.
