OK, so let's make the bit RO, and add VIRTIO_NET_CTRL_ANNOUNCED to acknowledge that we've seen VIRTIO_NET_S_ANNOUNCE using the control VQ?Thanks, that's nice. Guest should send arp packets first, then send VIRTIO_NET_CTRL_ANNOUNCED, and ignore the bit being set in the meantime. Thanks, Rusty.
Sure, I would update and re-send the spec updating patch. Thanks
