And I really don’t think it belongs in cake.  Not unless we put a complete DSCP re-marking system in there, which would massively complicate the configuration interface, which we don’t want to do.

Let me emphasise: cake can already *ignore* DSCP.  So can anything else in a network, with the possible exception of stupid wifi interfaces, which in the long run we should try to fix.  If you’re using Diffserv internally, then you already have a re-marking system separate from cake, which can do the squashing for you.

And, on a more technical note, adding squashing means cake crosses a threshold - from not modifying packets (except for ECN marking, which has a special function for the job) to doing so.  I’d rather have a separate, specialised qdisc for the re-marking task, and put squashing in there instead.

This is perhaps fairer comment, since I don’t expect many people will use it.  But since it’s already in there, and isn’t very much code, it might not make sense to remove it.
