Don Lewis e47145b6d3 MFC r318527 ... Fix the queue delay estimation in PIE/FQ-PIE when the timestamp (TS) method is used. When packet timestamp is used, the "current_qdelay" keeps storing the last queue delay value calculated in the dequeue function. Therefore, when a burst of packets arrives followed by a pause, the "current_qdelay" will store a high value caused by the burst and stick to that value during the pause because the queue delay measurement is done inside the dequeue function. This causes the drop probability calculation function to calculate high drop probability value instead of zero and prevents the burst allowance mechanism from working properly. Fix this problem by resetting "current_qdelay" inside the drop probability calculation function when the queue length is zero and TS option is used.
