+554 & 16 Feb 2016 & Thomas Huth & {virtio-net: fix inconsistent legacy header size
+
+ Current text says:
+ The legacy driver only presented num_buffers in the struct
+ virtio_net_hdr when VIRTIO_NET_F_MRG_RXBUF was not negotiated;
+
+ Should be:
+ "\dots was negotiated \dots" instead of "\dots was not negotiated \dots"
+
+ To be consistent with the following:
+ without that feature the structure was 2 bytes shorter.
+
+See \ref{sec:Device Types / Network Device / Device Operation / Legacy Interface: Device Operation}.

+555 & 16 Feb 2016 & Michael S. Tsirkin & {virtio header: tweak
+change motivation
+
+ The changes are not just to remove Linux assumptions,
+ we have also renamed ring->queue.
+ Tweak the header description accordingly.
+
+See \ref{sec:Basic Facilities of a Virtio Device / Virtqueues / Helpers for Operating Virtqueues}.

+558 & 16 Feb 2016 & Michael S. Tsirkin & {rename virtio_ring.h to virtio_queue.h
+
+ Since vring* and VRING* have been replaced with virtq* and VIRTQ*
+ respectively, rename the header virtio_ring.h to virtio_queue.h.
+
+See \ref{sec:virtio-queue.h}.

+559 & 16 Feb 2016 & Michael S. Tsirkin & {init: sort status bits
+
+ Status bit order is inconsistent: they are neither in increasing
+ order nor in the order they are likely to be used.
+
+ The second approach seems more useful since there aren't
+ that many bits, so the numerical order does not help much.
+
+ A typical order of use would be:
+
+\begin{itemize}
+\item ACKNOWLEDGE
+\item DRIVER
+\item then either FAILED or FEATURES_OK
+\item then either FAILED or DRIVER_OK
+\item then DEVICE_NEEDS_RESET (if device detects an error)
+\end{itemize}
+
+ Sort the bits accordingly.
+
+See \ref{sec:Basic Facilities of a Virtio Device / Device Status Field}.
