Bringing vDPA to Life in Kubernetes
summary
vDPA is integrated into Kubernetes by adding a secondary interface via Multus and the SR‑IOV device plugin, creating a device infospec JSON to tie device metadata to network attachments, and extending the device plugin, CNI and app.net util to recognize vhost‑vdpa and virtio‑vdpa. Demo runs on ConnectX‑6 Dx with four precreated VFs (two bound to virtio‑vdpa, two to vhost‑vdpa), runs DPDK testpmd generator and receiver, and shows wirespeed packet flow. Upstream kernel/DPDK support exists; management tools and a few protocol gaps remain.
