Previously I use kernel ovs, and docker veth-pair port can be added to ovs bridge directly. In this case, docker traffic from kernel will direct to ovs kernel module.
Now I want to use ovs+dpdk to speed up the forwarding performance, but I am wondering how docker traffic would go to ovs userspace bridge. From my understanding, veth-pair traffic would
always go from kernel, and it needs to be copied to userspace, then bridged by ovs+dpdk. The performance is quite low.
1) What is the proposed docker network port for ovs+dpdk? Ideally kernel should NOT be involved. I am not sure whether it is possible.
2) currently veth-pair port can only be handled by main thread (NON_PMD_CORE_ID) since its is_pmd attributes is false. This means it can only be handled by 1 CPU. How can multiple CPU handle such case?
