Why ? Isn''t the mapping done automatically based on the packet TOS ?
At least accoding to http://www.opalsoft.net/qos/DS-23.htm
"If you do not provide tc filters to classify traffic", the PRIO
qdisc looks at the TC_PRIO
priority to decide how to enqueue traffic. The kernel assigns each
packet a TC_PRIO priority,
based on TOS flags or socket options passed by the application.
The TC_PRIO is decided based on the TOS, and mapped as follows:"
