I'm using the old cobalt branch with the version after ingress mode was 
implemented.

tc-cake is configured with ingress mode and bandwidth 18800Kbit.

Downloading from a server with 2x16 connections using two aria2c 
processes, ~35ms ping latency to the server, I get about 18.7 Mbit/s 
received bytes on the interface (/proc/net/dev).
The remaining gross download rate is about 17.3 Mbit/s. That also 
matches the qdisc stats (drops/pkts = roughly 8%).
