Do you know the meaning of the "handle" argument to the cls_flow

following error, but I haven't yet found an explanation of what the
argument does, or what value it should take:
It doesn't seem to affect anything in my tests whatever value it has.
The code shows it gets used if the major id is 0 and for change - I
couldn't come up with a working test that used this.
I want to share 1.5mbit fairly among hosts (per-host fair queuing), my
work in progress script is as follows:
I don't think using just one queue for upload and download will be very
nice - I would use htb and try and separate up and down, you can make
them share/borrow so that you don't go over the 1.5mbit.
You may need to set the bandwidth to < 1.5mbit to get proper control.

I don't think putting flow on the real if will work with mirred - it
would need to be on ifb and attached to the sfq(s).
I don't think (but am not sure) that nfct-dst will work on ingress as
the packet hasn't hit netfilter yet. If your openwrt is just routing and
doesn't have significant traffic to/from it apart from internet then you
could redirect from egress on the lan facing if(s) rather than ingress.
