Please remind to use --in-reply-to. Just looking at the title, we should not take it for RC3. But reading the commit message, especially "this leads to a complete misinterpretation of the packet type being received", it appears fixing a real bug. In this case, the title should be "net/mlx4: fix Rx packet type offloads"
