With bandwidth-based multicast suppression, the bandwidth
is measured in Kbps.
The upper limit of the multicast suppession with bandwidth-based(Kbps)
is the value of hwifBKbpsMulSuppressionMax in the entry.
The value of hwifBKbpsMulSuppression must be multiple of the
value of hwifBKbpsMulSuppressionStep.
The default value of hwifBKbpsMulSuppression is the value of
hwifBKbpsMulSuppressionMax.
