(Error checking in qdiscs would be cool, I like error messages even that just say -EINVAL). I can't think of any other way to check, but I had a look in ceropackages-3.10.git. It should be up to date, it fetches the specific git commit (by sha1) that's on the head of the cake repo :(. Strange failure on Dave's build if it's not. I ran sqm-scripts to pass atm/40 to cake. Here's what that looks like. Did you mean me to run some load first, if so what sort?
