If you want to achieve that then you need to do it differently. The prio
in the filter above is matching the packet's prio field and filtering
traffic in as appropriate, so the only traffic going into the leaf above
is that with a prio value 4 (which would explain why no shaping is
taking place).

If you want to do the prio stuff, you'll need to attach it as a separate
qdisc to the appropriate class, but again remember that it will only do
that for each user within that leaf class.

In which case there's no need to add any P2P rules in this instance,
unless you want to shape individual users' traffic for them.
