Have a 🍰! Jonas’ (TU Berlin) and Toke’s (Red Hat) multi-queue aware network scheduler cake_mq has been upstreamed and will appear in the upcoming version 7.0 of the Linux kernel. Congratulations!

cake_mq will better scale the network traffic rate shaper across multiple CPU cores. For a research paper see https://schmiste.github.io/lanman25.pdf (IEEE LANMAN 2025).
