Bug description:
  Openstack + ovs 1.4.6-0ubuntu1.12.04.4 + kernel 3.2.0-70 and newer
  crash on first gre traffic

  [Impact]

   * Openstack + ovs 1.4.6-0ubuntu1.12.04.4 + kernel 3.2.0-70 and newer crash on first gre traffic
   * Kernels newer than 3.2.0-70 are not able to be used with the openvswitch module built using 1.4.6-0ubuntu1.12.04.4 

  [Test Case]

   1. Deploy grizzly openstack with Openvswitch for neutron.
   2. Upgrade kernel on compute host to greater than 3.2.0-69
   3. Deploy and boot VM.
   4. Associate IP with VM
   5. Ping VM
   6. Watch compute host crash.

  [Regression Potential]

   * Few character change
   * This has been broken since release of 3.2.0-70
   * Users should have already migrated Openstack clouds off of Grizzle + precise.

  [Other Info]
   
   * 3.13 kernel ships with ovs module included in the kernel.
