divide IP datagram into 64 priorities. When DSCP Priority is enabled, IP
datagram are mapped to different priority levels based on DSCP priority mode;
non-IP datagram with IEEE 802.1Q tag are mapped to different priority levels
based on IEEE 802.1P priority mode if IEEE 802.1P Priority is enabled; the
untagged non-IP datagram are mapped based on port priority mode.

dscp-list —— List of DSCP value. One or several DSCP values can be typed
using comma to separate. Use a hyphen to designate a range of values, for
instance, 1,4-7,11 indicates choosing 1,4,5,6,7,11. The DSCP value ranges
from 0 to 63.
tc-id —— The egress queue the packets with tag are mapped to. It ranges from
0 to 3, which represents TC0, TC1, TC2, TC3 respectively.

1. By default, the mapping relation between tag and the egress queue is:
(0-15)-TC0, (16-31)-TC1, (32-47)-TC2, (48-63)-TC3
2. Among the priority levels TC0-TC3, the bigger value, the higher
priority.

When the network is congested, the program that many packets complete for
resources must be solved, usually in the way of queue scheduling. The switch
will control the forwarding sequence of the packets according to the priority
