The value of tmnxAncpPlcyIngRateReduction specifies the rate adjustment
for the scheduler. This object should be used when the rate returned
by the the DSLAM is calculated with a different encapsulation than the
7xxx. The node will adjust the rate by the indicated percent as:
DSLAM_RATE * tmnxAncpPlcyIngRateAdjustment/100 - tmnxAncpPlcyIngRateReduction.
