But it's still not working?

I assume that you're definitely checking packets from squid to the
*client* that made the original file request?

Any value will work, and it's easy to see if a packet's been marked just
by using a -j LOG rule. As an aside, depending on what you are trying to
do, netfilter marks are a much more flexible solution.

Anyway, to further debug this, can you please wind the debug level up to
3 or greater. If setting the TOS is failing then you will see something
like:

Ip::Qos::setSockTos: setsockopt(IP_TOS) on ...

If you don't see that, then search for the string
"tos" (case-insensitive) in the logs and see if you can see any other
TOS related messages.

Failing any of that, I'll write a patch in order to debug further.
