[LARTC] Problem with flowid filter example from howto

[LARTC] Problem with flowid filter example from howto

[Andrew D]

For simplicity, I tried this:

tc qdisc add dev eth0 root handle 1: prio
tc qdisc add dev eth0 parent 1:1 handle 10: sfq perturb 10
tc qdisc add dev eth0 parent 1:2 handle 20: sfq perturb 10
tc qdisc add dev eth0 parent 1:3 handle 30: sfq perturb 10

tc filter add dev eth0 protocol ip parent 1: prio 2 flowid 1:1

The last line prints:
Unknown filter "flowid", hence option "1:1" is unparsable

I'm pretty sure that last line is almost exactly what is printed
in the howto, translated for what I want.  Did I need to add
something else first?  If this is not the right syntax, how do I
make all traffic (for now) go to a specific flow?

Try 
tc filter add dev eth0 protocol ip parent 1: src 0/0 prio 2 flowid 1:1

Thanks.  Though it doesn't quite work, I messed around with it till I
got this which does:

tc filter add dev eth0 protocol ip parent 1: prio 2 u32 match \
  ip src 0/0 flowid 1:1

Seems like an extra "if" statement, but it does the job.  Now I am
wondering, is this wrong in the howto (section 9.6.1) or is my system
just broken?

I think you can say it's a features that's missing in tc :)
You have to match something, if if you match everything.
