In this context, the MBS is the burst tolerance of the policer's leaky
bucket for high priority traffic. On ingress, this is trusted in-profile
packets and untrusted high priority packets.
There's an explanation in the SR OS QoS Configuration Guide. Search for
the context "config>qos>sap-ingress>policer".
The default MBS is 64 kilobytes when PIR = max, otherwise, 10ms volume
of traffic for a configured non zero/non max PIR.
