Accelerate containers and VMs networking with vDPA
summary
vDPA offloads both data and control planes to smart NICs to give containers and VMs a virtio HW offload that preserves the standard virtio interface while decoupling images from NIC firmware. Implementation uses a vDPA kernel framework plus vendor translation drivers and user-space DPDK PMDs, integrated into Kubernetes as a Multus secondary interface. A live demo runs on a real NIC with back-to-back containers, showing one CPU handling about 20k TCP connections and roughly 160k packets/sec.
