Hi

I missed that, thanks.  (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?

Regards
Alan
