The suspention time for the class is only 26usec (shown as offtime
in the altqstat output) but the timer granularity is too coarse and
it takes much longer to actually resume the class.
As a result, arriving packets during this period are stored in the
queue until the queue overflows.  The class actually lost several
packets (shown as "drops" in the altqstat output).
