Hi, I have retrying from the beginning with a empty ovs database and the 
ovs module unloaded

I still have this errors when I create the bridge

root at g3:/var/lib/openvswitch# ovs-vsctl add-port  br-eth0 eth0
[ 2279.939240] device eth0 entered promiscuous mode


root at g3:/var/lib/openvswitch# ip link set eth0 up
root at g3:/var/lib/openvswitch# ip link set br-eth0 up


# ovs-vsctl show

     Bridge "br-eth0"
         Port "eth0"
             Interface "eth0"
         Port "br-eth0"
             Interface "br-eth0"
                 type: internal
     ovs_version: "2.3.0"


But this bridge doesn't works. I test by just setting a ip on br-eth0 
and pinging an other machine on the same lan.

The same manipulation with kernel (with builtin ovs module) 3.14 and ovs 
(userland) 2.3.0 and I have no error message and the bridge works.

Tell me if you need a particular command output.
