+ * Algorithm parameters, tunable via debugfs.
+ * @dir: the debugfs directory for a specific phy
+ * @target: target percentage for failed frames
+ * @sampling_period: error sampling interval in milliseconds
+ * @coeff_p: absolute value of the proportional coefficient
+ * @coeff_i: absolute value of the integral coefficient
+ * @coeff_d: absolute value of the derivative coefficient
+ * @smoothing_shift: absolute value of the integral smoothing factor (i.e.
+ * amount of smoothing introduced by the exponential moving average)
+ * @sharpen_factor: absolute value of the derivative sharpening factor (i.e.
+ * amount of emphasis given to the derivative term after low activity
+ * events)
+ * @sharpen_duration: duration of the sharpening effect after the detected low
+ * activity event, relative to sampling_period
+ * @norm_offset: amount of normalization periodically performed on the learnt
+ * rate behaviour values (lower means we should trust more what we learnt
+ * about behaviour of rates, higher means we should trust more the natural
+ * ordering of rates)
+ * @fast_start: if Y, push high rates right after initialization
