Hi Ilya,
Thanks for the patch set which adds the dpif hint inside the netdev struct. It
is really helpful.
Our goal is to have flow_put() calls on vxlan devices, using the existing dpdk
flow API.
We added logic inside netdev_dpdk_flow_api_supported() to accept vxlan devices
and indeed
we see

BTW, few nits about patch submission for a next time:
* Commonly in OVS patch subject should start with a capital letter
