* struct rc_pid_debugfs_entries - tunable parameters
*
* 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
