Hi, all,

according to the following HTML, 
http://lartc.org/howto/lartc.qdisc.classful.html
section 9.5.3.1. PRIO parameters & usage: 
it says:
"If you do not provide tc filters to classify traffic, the PRIO qdisc
looks at the TC_PRIO priority to decide how to enqueue traffic."

So my understanding is that the Priomap will be consulted to classify
the packet. 
However, I see the packet always goes into the "best-effort" queue, i.e.
band1, the medium priority queue, no matter how I change the TOS byte of
the packet.

Can someone point out whether I have a misunderstanding of this or there
is a discrepancy between the behavior and the code? Thanks very much.
