Hi Luca, It looks like Ubuntu backported a custom fix into some of their newer kernels, leading to this build breakage in conjunction with OVS-2.5.0 dkms. I didn't see a problem with some 3.16.0-5x versions. If it's viable, you can just use the openvswitch module that comes with the Ubuntu kernel. Alternatively to fix it, you'll need to apply this patch to your tree (picking up branch-2.5 on github should also fix the issue): https://github.com/openvswitch/ovs/commit/a35342879f1a7d8b1503d4945bd0791c58f5fc87 _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
