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
