Control a network device notifications coalescing parameters using the control virtqueue.
A new control class was added: VIRTIO_NET_CTRL_NOTF_COAL.
This class provides 2 commands:
\begin{itemize}
\item VIRTIO_NET_CTRL_NOTF_COAL_TX_SET:
Ask the network device to change the tx_usecs and tx_max_packets parameters.
\begin{itemize}
\item tx_usecs: Maximum number of usecs to delay a TX notification.
\item tx_max_packets: Maximum number of packets to send before a TX notification.
\end{itemize}
\item VIRTIO_NET_CTRL_NOTF_COAL_RX_SET:
Ask the network device to change the rx_usecs and rx_max_packets parameters.
\begin{itemize}
\item rx_usecs: Maximum number of usecs to delay a RX notification.
\item rx_max_packets: Maximum number of packets to receive before a RX notification.

26ed30ccb049 & 03 Aug 2022 & Stefano Garzarella & {\noindent virtio-vsock: add VIRTIO_VSOCK_F_NO_IMPLIED_STREAM feature bit\vspace{\baselineskip}
Initially virtio-vsock only supported the stream type, which is why
there was no feature. Later we added the seqpacket type and in the future
we may have other types (e.g. datagram).
seqpacket is an extension of stream, so it might be implied that if
seqpacket is supported, stream is too, but this might not be true for
other types.
As we discussed here [1] should be better to add a new
VIRTIO_VSOCK_F_NO_IMPLIED_STREAM feature bit to avoid this implication.
Let's also add normative sections to better define the behavior when
VIRTIO_VSOCK_F_NO_IMPLIED_STREAM is negotiated or not.

b4e8efa0fa6c & 05 Dec 2022 & Dmitry Fomichev & {\noindent virtio-blk: add zoned block device specification\vspace{\baselineskip}
Introduce support for Zoned Block Devices to virtio.
Zoned Block Devices (ZBDs) aim to achieve a better capacity, latency
and/or cost characteristics compared to commonly available block
devices by getting the entire LBA space of the device divided to block
regions that are much larger than the LBA size. These regions are
called zones and they can only be written sequentially. More details
about ZBDs can be found at
\url{https://zonedstorage.io/docs/introduction/zoned-storage} .
In its current form, the virtio protocol for block devices (virtio-blk)
is not aware of ZBDs but it allows the driver to successfully scan a
host-managed drive provided by the virtio block device. As the result,
the host-managed drive is recognized by virtio driver as a regular,
non-zoned drive that will operate erroneously under the most common
write workloads. Host-aware ZBDs are currently usable, but their
performance may not be optimal because the driver can only see them as
non-zoned block devices.
To fix this, the virtio-blk protocol needs to be extended to add the
capabilities to convey the zone characteristics of ZBDs at the device
side to the driver and to provide support for ZBD-specific commands -
Report Zones, four zone operations (Open, Close, Finish and Reset) and
(optionally) Zone Append. The proposed standard extension aims to
define this new functionality.
This patch extends the virtio-blk section of virtio specification with
the minimum set of requirements that are necessary to support ZBDs.
The resulting device model is a subset of the models defined in ZAC/ZBC
and ZNS standards documents. The included functionality mirrors
the existing Linux kernel block layer ZBD support and should be
sufficient to handle the host-managed and host-aware HDDs that are on
the market today as well as ZNS SSDs that are entering the market at
the time of submission of this patch.
I would like to thank the following people for their useful feedback
and suggestions while working on the initial iterations of this patch.

\item Consolidating virtio_net_ctrl_coal_tx and virtio_net_ctrl_coal_rx
into a single struct, virtio_net_ctrl_coal, as they are identical.
\item Emphasizing that the coalescing commands are best-effort.
\item Defining the behavior of coalescing with regards to delivering
notifications when a change occur.
\item Stating that the commands should apply to all the receive/transmit
virtqueues.
\item Stating that every receive/transmit virtqueue should count it's own
packets.
\item A new intro explaining the entire coalescing operation.

3508347769af & 01 Mar 2023 & Parav Pandit & {\noindent virtio-net: Improve introductory description\vspace{\baselineskip}
The control VQ of the virtio network device is used beyond advance
steering control. The control VQ dynamically changes multiple features
of the initialized device.
Hence, update this area of control VQ introductory description at few
places and also place the link to its description.
Also update the introduction section to better describe receive and
transmit virtqueues.
