Hi Ilya,
No, we didn't test this patch based on OVS-AF_XDP, but made a black build to
enable this in OVS-DPDK and test it.
Currently DPDK-AF_XDP has been tested in latest kernel (not released). So I
think OVS-AF_XDP is close to be supported for aarch64.
Furthermore, I found a document about

We are working to support arm64 build for ovs travis CI. It is indeed to use

Hi James,
CRC32 is not a mandatory feature for Armv8.0. What is the arm64 CPU used in
your platform?
I'm not sure if it's necessary to use mandatory feature (neon) to optimize hash
libraries, because I thought most arm64 CPUs supported CRC32.

I think the main objective of this patch is to introduce AF_XDP socket for OVS
