the priority and bandwidth are not congestion avoidance mechanisms so it
mean that in order for them to take effect there need to be congestion so
that is not answering the requirement of never be congested.
for the line to never be congested there need to be usage of Police and WRED
as WRED can work for TCP flows Police can work for all the rest.
