You would need to use partial contents from patch :
http://patchwork.ozlabs.org/project/openvswitch/patch/1608142365-26215-1-git-send-email-ian.stokes@intel.com/

If you'd like me to send patches which would work with 2.13, 2.14, I'm ok with that too.[keeping only those parts from patch which fixes the issue you see.]
But we must ensure it doesn’t cause problems for OVS too.
Your thoughts Ilya ?
