vDPA Support in Linux Kernel
summary
Defines a new hardware class, the vDPA device, that exposes a virtio-compatible data plane and a vendor-specific control path and builds a kernel vDPA framework that maps those devices into the kernel and userspace stacks. Core bus and APIs are merged and three parent backends exist today: Intel VF, Mellanox VF, simulator. QEMU vhost support is merged, netlink management and live migration are under development, and the goal is full wire speed offload with both vhost and virt bus drivers available.
