Okay, the ovs I had before this was 2.5.0. Which was pretty much perfect.
The one I have now on standalone hardware with Yocto is openvswitch-2.0.0 (Due
to some reason). Does this version not talk Openflow 1.3?
Should I enable openflow13 for my bridge explicitly like this ? :
ovs-vsctl set bridge br0 protocols=openflow10,openflow12,openflow13
Thanks,
Monica

Type 16, stat 12 is undefined in OpenFlow 1.0 (version 1). In OpenFlow
1.3 it is OFPST_TABLE_FEATURES_REQUEST. Maybe the controller is trying to make
that request in version 1.0; it's not going to work there.
Just a guess though.
