[ovs-discuss] OvS-DPDK vs XDP-eBPF performance numbers - for linux container

Are there 'numbers'  for performance - OvS-DPDK  vs XDP-eBPF for container networking.

Since the DPDK and linux-containers are not compatible, is a sense that container and host share the same kernel - hence pkts received at OvS-DPDK  at user-space and directed to a linux container  - should be go   down to the kernel and then to the container ip-stack, while in XDP-eBPF this pkt can be forward to the container ip-stack directly from the kernel.

I heard that a vhostuser interface for containers is 'in-working' stage.
Can anyone assist with the performance numbers and the status of this vhost-user for containers ?

Best Regards
