Ah. Right, we need to trap for host to clear the bit.
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
