Yes, you definitely need to use CONNMARK, not MARK.

I used (and created) the patch to get the value from the remote server.
However, I can't remember whether it does it the other way as well (at
the time I thought I'd written the documentation so clearly, but coming
back to it now it's not clear...)

From memory, however, you do need to configure qos_flows to *something*,
to trigger its operation. I think you can simply state "qos_flows mark".

As above, it's primarily server to client. Get that working first so you
know everything is in order, and then try it the other way.

Let me know what you find out and I will update the documentation! (I
don't have time to look through the source code right now)
