Because you are using gre try:
ovs-ofctl dump-flows br-int/br-tun
ovs-dpctl dump-flows br-int/br-tun

If you can upgrade to more recent openvswitch there is a great trace
function implemented.

I have also experienced problems with quantum and gre:

I will review your configuration and let you know whether I see any
potential issues.
