Hi Kanthi, In the case of OVS AF_XDP netdev, we've used multiple PMD threads. Each thread has its own AF_XDP socket and its own UMEM bind to each rx queue. I think multiple processes should also work.

Sorry, I mean AF_XDP for veth driver. Thank you William

The patch adds the test framework for OVS using afxdp. Most of the test cases are slightly modified from the existing test cases at system-traffic.at. All the veth creations, ADD_VETH, are replaced by

There are still two issues causing some test cases failed. This patch provides an work-around. Signed-off-by: William Tu <u9012063@...> --- lib/dpif-netdev.c | 2 +- tests/system-afxdp-macros.at

The patch creates a new netdev type called "afxdp" and re-uses some of the AF_XDP API implementation from xdpsock_user.c at linux sample code. By default, it binds a device's queue 0 and uses the gene

The patch series introduces AF_XDP support for OVS netdev. AF_XDP is a new address family working together with eBPF. In short, a socket with AF_XDP family can receive and send packets from an eBPF/XD
