to a CoS that is mapped from the PCP and DEI value in the tag. Otherwise the
frame is classified to the default CoS.
The classified CoS can be overruled by a QCL entry.
Note: If the default CoS has been dynamically changed, then the actual default
CoS is shown in parentheses after the configured default CoS.
