Upon receiving a packet, the switch allocates a service group set to it, including CoS
value, local precedence value, drop-precedence. The allocation rule is based on the
packet 802.1p priority: use the 802.1p priority value as the CoS value, obtain local
precedence value and drop-precedence respectively from "CoS → Local-precedence"
mapping table and "CoS → Drop-precedence" mapping table.
