I can't find any documentation on the paramaters for the ingress qdisc. Can someone help me? I have a number of filters feeding into my ingress qdisc, all of which are rate limited, but I want to place a limit on the aggregate flow as well. I don't want to monitor the sum of the flow rates - I want to place a hard ceiling on the total possible flow that overrides everything else. Any further details about the internal workings of the ingress qdisc would also be very helpful. I've seen some stuff that suggests its really a TBF in disguise, but I'm not sure. In particular, I'd like to understand if the flows into the ingress qdisc can borrow from the root and/or each other. Also, since the ingress qdisc is classless, how does it work that each of the incoming flows are separately metered? (As I understand it, filters only serve to guide packets into classes) I know that the IMQ device offers a more sophisticated way to do this but, for now, that device is not available to me. I need answers to these specific questions, but I very much appreciate any other information anyone would like to volunteer.
