C++ definition

Sets the DSCP field (lower six bit of Tos/TrafficClass) of IP datagrams to the value specified by the dscps parameter.

The dscps parameter is a space-separated list of DSCP values. Packets arriving at gate in[i] are marked with the ith value. If there are fewer DSCP values given than input gates, then the last one is repeated.
