To specify local priority for packets is the prerequisite for queue scheduling. For packets from
the upstream device, you cannot only map the external priority carried by packets to different
local priority, but also configure local priority for packets based on interface, then the
A10E/A28E will take queue scheduling according to local priority of packets. Generally
speaking, IP packets need to configure mapping relationship between IP priority/DSCP
priority and local priority; while VLAN packets need to configure mapping relationship
between CoS priority and local priority.
