A Set Request for rmIfOutPacingRateRequested that does not
reduce the port rate below the currently allocated bandwidth
guarantees for the output flow always succeeds irrespective
of the value of rmIfOutPacingForce. But a Set Request for
rmIfOutPacingRateRequested that does reduce the port rate
below the currently allocated bandwidth guarantees for the
output flow will succeed only if rmIfOutPacingForce object
is also set to the value forceChange. In either of the above
cases, once rmIfOutPacingRateRequested object is set to the
appropriate value, rmIfOutPacingForce object assumes the
noForceChange value. This object is not instantiated for
interfaces to which it cannot be applied.
