NOTE: We only have two modes now. The mode is not equal to the command. We can add VIRTIO_NET_CTRL_MQ_TUNNEL_CONFIG for commands, but there are still only two modes:"This specification defines the following modes that a device MAY implement for operation with multiple transmit/receive virtqueues:\begin{itemize}\item Automatic receive steering as defined in \ref{sec:Device Types / Network Device / Device Operation / Control Virtqueue / Automatic receive steering in multiqueue mode}. Â If a device supports this mode, it offers the VIRTIO_NET_F_MQ feature bit. \item Receive-side scaling as defined in \ref{devicenormative:Device Types / Network Device / Device Operation / Control Virtqueue / Receive-side scaling (RSS) / RSS processing}. Â If a device supports this mode, it offers the VIRTIO_NET_F_RSS feature bit.\end{itemize}
So, it is not incorrect that we put VIRTIO_NET_CTRL_MQ_TUNNEL_CONFIG here.
Got it. I got confused between mode and command with the text "The command selects the mode of multiqueue operation, as follows:" But its clear to me now. Thanks.
