Jarek,
iptables chains (this is what I think you are referring to) are not the issue. This
is about the qdisc that sits immediately over the device driver and decides the
order waiting packets are sent over the line/air/carrier pigeon/... .
My suspicion is that skb->priority used to be set to a value that derived from the
TOS bits. Then something changed and nobody noticed.

...Too exactly! Iptables aren't needed for this, so "going through
the forward." should be enough...
