Well yes, that's the whole point - at least as far as the shaper is concerned.  Ingress mode is supposed to deal with the case where inbound packets have already traversed the bottleneck link *before* Cake gets to choose what to do with them.

But that shouldn't affect fairness, only total throughput.  Fairness is not handled by the shaper, but by the (very) extended DRR++ algorithm.
