Red Hat engineers have been developing virtual data path acceleration (vDPA) as a standard data plane that is more flexible than VirtIO full hardware offloading. The goal is providing wire-speed Ethernet interfaces to virtual machines in an open manner.
This patch series was sent out on Thursday by Red Hat's Jason Wang. This implements the vDPA bus for the Linux kernel as well as providing a vDPA device simulator and supporting vDPA-based transport within VirtIO.
