The ingress qdisc itself has no parameters.  The only thing you can do is 
using the policers.  I have a link with a patch to extend this :

I have some more info about ingress in my mail files, but I have to sort it 
out and put it somewhere on docum.org.  But I still didn't found the the time 
to do so.
