Re: [LARTC] Limit for prio value

[Vinod Chandran <vinod_chandran@multitech.co.in>]

Hi all,

While surfing the code I happened to land on the following piece of code 
in the file net/sched/sch_htb.c.

if ((cl->un.leaf.prio = hopt->prio) >= TC_HTB_NUMPRIO)
                        cl->un.leaf.prio = TC_HTB_NUMPRIO - 1;

NUMPRIO is defined to eight, hence I feel the behavior.
I will be trying to change this value, still any idea behind this logic.

Thanks,
Vinod  C
