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}.
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}.
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.
