With bandwidth-based unicast suppression, the bandwidth
is measured in Kbps.
The upper limit of the unicast suppession with bandwidth-based(Kbps)
is the value of hwifBKbpsUniSuppressionMax in the entry.
The value of hwifBKbpsUniSuppression must be multiple of the
value of hwifBKbpsUniSuppressionStep.
The default value of hwifBKbpsUniSuppression is the value of
hwifBKbpsUniSuppressionMax.
