This is what I have done, the  cl->rate->rate.rate refers to the __u32
rate in htb_class -> qdisc_rate_table -> tc_ratespec .
What else should I modify to make this work ?

Hi everyone,

I am trying to change the rate parameter of HTB class by using this
code from within one of my functions :

   struct htb_class *cl;
   cl=htb_find(number,q);

   cl->rate->rate.rate = NEW_RATE_VALUE;

   TC shows the correct values, but the traffic rate doesn't change a
bit.
   Does anyone have any idea what am I doing wrong ? Maybe there would
be a faster way by sending a netlink  message ?

HTB uses a rate table, so if you want the rate to change, you will need to change the
table as well.
