- *	1. if a packet arrives for a not-overlimit class, set cutoff
- *	   to the depth of the class.
- *	2. if cutoff is i, and a packet arrives for an overlimit class
- *	   with an underlimit ancestor at a lower level than i (say j),
- *	   then set cutoff to j.

- * rm_class_t *
- * rmc_newclass(...) - Create a new resource management class at priority
- * 'pri' on the interface given by 'ifd'.
- *
- * nsecPerByte  is the data rate of the interface in nanoseconds/byte.
- *              E.g., 800 for a 10Mb/s ethernet.  If the class gets less
- *              than 100% of the bandwidth, this number should be the
- *              'effective' rate for the class.  Let f be the
- *              bandwidth fraction allocated to this class, and let
- *              nsPerByte be the data rate of the output link in
- *              nanoseconds/byte.  Then nsecPerByte is set to
- *              nsPerByte / f.  E.g., 1600 (= 800 / .5)
- *              for a class that gets 50% of an ethernet's bandwidth.
- *
- * action       the routine to call when the class is over limit.
- *
- * maxq         max allowable queue size for class (in packets).
- *
- * parent       parent class pointer.
- *
- * borrow       class to borrow from (should be either 'parent' or null).
- *
- * maxidle      max value allowed for class 'idle' time estimate (this
- *              parameter determines how large an initial burst of packets
- *              can be before overlimit action is invoked.
- *
- * offtime      how long 'delay' action will delay when class goes over
- *              limit (this parameter determines the steady-state burst
- *              size when a class is running over its limit).
- *
- * Maxidle and offtime have to be computed from the following:  If the
- * average packet size is s, the bandwidth fraction allocated to this
- * class is f, we want to allow b packet bursts, and the gain of the
- * averaging filter is g (= 1 - 2^(-RM_FILTER_GAIN)), then:
- *
- *   ptime = s * nsPerByte * (1 - f) / f
- *   maxidle = ptime * (1 - g^b) / g^b
- *   minidle = -ptime * (1 / (f - 1))
- *   offtime = ptime * (1 + 1/(1 - g) * (1 - g^(b - 1)) / g^(b - 1)
- *
- * Operationally, it's convenient to specify maxidle & offtime in units
- * independent of the link bandwidth so the maxidle & offtime passed to
- * this routine are the above values multiplied by 8*f/(1000*nsPerByte).
- * (The constant factor is a scale factor needed to make the parameters
- * integers.  This scaling also means that the 'unscaled' values of
- * maxidle*nsecPerByte/8 and offtime*nsecPerByte/8 will be in microseconds,
- * not nanoseconds.)  Also note that the 'idle' filter computation keeps
- * an estimate scaled upward by 2^RM_FILTER_GAIN so the passed value of
- * maxidle also must be scaled upward by this value.  Thus, the passed
- * values for maxidle and offtime can be computed as follows:
- *
- * maxidle = maxidle * 2^RM_FILTER_GAIN * 8 / (1000 * nsecPerByte)
- * offtime = offtime * 8 / (1000 * nsecPerByte)
- *
- * When USE_HRTIME is employed, then maxidle and offtime become:
- * 	maxidle = maxilde * (8.0 / nsecPerByte);
- * 	offtime = offtime * (8.0 / nsecPerByte);
