OLD: * Delay specified in ticks. * Drop performed as packets were leaving the delay queue (i.e., leaving dummynet). This is more accurate in terms of calculating time spent in dummynet, and can be used with all strategies of BW/delay shaping (constant values, distributions, table lookup), but required that ultimately-dropped packets get put on the BW queue, changing the timing of things. NEW: * Delay specified in milliseconds. * Drops perfromed as packets enter the bandwidth queue (i.e., arrive in dummynet). Here drops are based on estimates of how long a packet would spend in dummynet and thus only works with constant delay/BW shaping characteristics, but does more accurately reflect queuing behavior. The estimate is done by looking at the length in bytes of the bandwidth queue (including the candidate packet) for the pipe, determining how long it will take to transmit that many bytes, and then adding the delay value for the pipe.
