What userspace do "802.1ad patches" depend on? Per Pravin's statement, we just
backport 802.1ad patches to ovs, then the below patch can be applied to ovs.

I had replied to Pravin earlier in this thread.
I do intend to backport the kernel changes to the ovs out-of-tree module. I was
waiting until userspace was ready. Unfortunately that's not likely to happen

If you have the time feel free to give it a go.
