Hi all,

When I try to run the ultimate traffic conditioner (cbq implementation), I get this strange output:

/tc# ./ultimate

/tc# tc filter show dev eth1

/tc#

As you can see, the script adds way to many u32 filters. I did some testing, and figured out the problem has something to do with the different priorities. when I give each u32 filter the same priority, I get the right number of filters.

Is this output correct? If not, what can be the problem?

thanks,
Jan
