[Description]
Changes the DSCP value of the classified traffic class to the specified DSCP value. In addition, reassign the egress queue

If this is executed with the "no" syntax, pre-marking processing of the DSCP value corresponding to the traffic class is
removed.

Pre-marking cannot be used in conjunction with the set egress queue function.
