tFilterRUTRespPrioChange specifies the amount of change
to be made to the priority of the destination if the
tFilterRUTRespAction is either 'increase' or 'decrease'.
If tFilterRUTRespAction is 'disable', tFilterRUTRespPrioChange will
be forced to 0. Any change to tFilterRUTRespPrioChange will be
silently discarded in this case.
Setting the object tFilterRUTRespPrioChange to 0 will cause the value of
tFilterRUTRespAction to be set to 'disable'.
