Thanks, very good to know.

To be clear, I have a series that doesn't use Open Flow 1.3.1 version
negotiation protocol but has been designed to allow it to be easily added.
And I have done some preparatory work on the Hello extension described in
Open Flow 1.3.1. So from here I see myself having two choices:

1. Post the series as is (very soon)
   - Actually its already in
     git://github.com/horms/openvswitch.git devel/of1.2-runtime-switch2
     but I am waiting to verify the presence or absence of a bug
     relating to selection of flow formats.

2. Add Open Flow 1.3.1 version negotiation and then post (a bit later)
