New OVS Linux datapath features are developed on top of the upstream net-next git repo. I have just addressed feedback on v4 and rebased to the now current net-next. OVS tree kernel module will be updated with NAT support (and backports as far as feasible) only after the code has been merged in net-next. If you want to test OVS NAT integration now you need to clone the net-next repo, apply the patches, compile a new kernel from there, and then run the OVS on top of the new kernel. To make this a bit easier I have created a bundle for these patches in patchwork: http://patchwork.ozlabs.org/bundle/jarno/OVS_NAT_v5/ <http://patchwork.ozlabs.org/bundle/jarno/OVS_NAT_v5/> You should be able to download the bundle and then apply it with “git am” to your local net-next repo.
