You are in a hurry - it was only released 10 hours ago :)

Yes, Michal has a patch almost ready to submit. I think it just a needs a final
test run now that DPDK 16.04 is released.
The patch will be for OVS master, not for OVS 2.5 branch. We haven't typically
backported newer versions of DPDK, although I suspect it would apply if you
wanted to use it with OVS 2.5.
