Problems :
1) By default, the controller does not start in exact match
mode, flows are always wildcarded, and there is no way to set matching
to exact match.
2) Still has normalisation errors :
In ovs-controller :

In ovs-openflowd :

What I don't understand is why both ovs-controller and
ovs-openflowd claim to do the same normalisation. It doe snot make
sense to me.
I think I remember that with the other patch, there were no
longer any normalisation warnings.
