...> to control packet flow within QEMU. (CC's reduced, context added, Dmitry Fleytman added for vmxnet3 thoughts). Then I'm really confused as to what this would look like. A zero copy sendmsg? We should be able to implement that today. On the receive side, what can we do better than readv? If we need to return to userspace to tell the guest that we've got a new packet, we don't win on latency. We might reduce syscall overhead with a multi-dimensional readv to read multiple packets at once? Confused, Rusty.
