DSCP value doesn't decide a service flow by itself. Usually CID is
determined in combination with the other values such as source/
destination addresses.

As of my knowledge, there is no rule to convert IPv6 DSCP (diffserv
codepoint) into 802.16 QoS parameter in a deterministic way. I
understand its up to the implementation & policy.

Thanks for your kind consideration.
