Comment 8 for bug 1787792

As discussed on PTG next steps can be:
1. Investigate how we can use Common Classifier Framework to associate QoS rules with some classifiers and apply it then only for specific class of traffic - then it will be able to use it for BW limit on FIP and on L2 port levels as well as for e.g. DSCP marking rules and other things,
2. Make some PoC of such solution or maybe find if there are other ways to do something like that,
3. In case of VPN QoS we will also have to implement some support for classful bw limits in tc driver so it may be reused in case of this RFE also.
