It can be implemented,but you cannot use the DSCP, because marking is the
last thing what you will do with packets. But you can use the
skb->tc_index for identify the packets/flows and you can modify it at the
ingress and egress too.Try it to understand in the "Differentiated
Services on Linux" how can you modify and use the skb->tc_index.
