Whenever the Cable Modem passes flap detection,
then the flap counter is increased.
There are 3 flap detectors defined:
(1) When ccsFlapInsertionFails is increased the Flap count
will be increased.
(2) When the CMTS receives a Miss followed by a Hit
then the Flap count will be increased.
(3) When ccsFlapPowerAdjustments is increased the Flap
count will be increased.
Discontinuites in the value of this counter can occur if
this entry is removed from the table and then re-added, and
are indicated by a change in the value of
ccsFlapCreateTime.
