Hello,

I am really not sure if this is the right place for this question, if not,
please just let me know.

Today I tried to follow the OVS Faucet Tutorial at:
http://docs.openvswitch.org/en/latest/tutorials/faucet/

Just as described, I cloned and checked out the master branch of ovs, and
the latest tag (v1.8.9) of faucet and worked with the ovs-sandbox.

I followed all the steps and added a bridge br0 with 5 ports.
But after dumping the flows of br0 (with the dump-flows() function) I get
a totally different output that what is described in the tutorial.
Because of this, the following tracing steps also don't work out, my
packet just gets dropped instantly in table 0.

Is this tutorial still up-to-date? Or did I just do something wrong?
Please find below the relevant outputs.
