similar to: [PATCH 0/2] vdpa/snet: support [s/g]et_vq_state and suspend

Add more vDPA callbacks. [s/g]et_vq_state is added in patch 1, including a new control mechanism to read data from the DPU. suspend is added in patch 2.

The callback sends a resume command to the DPU through the control mechanism.

Note: dropped some commits at the last moment, I did verify we get the same code in the end as what was in linux next for a while now.

At the moment, if a virtio network device uses vrings with less than MAX_SKB_FRAGS + 2 entries, the device won't be functional. The following condition vq->num_free >= 2 + MAX_SKB_FRAGS will always evaluate to false, leading to TX timeouts. This patchset attempts this fix this bug, and to allow small rings down to 4 entries. The first patch introduces a new mechanism in virtio core -

Hi, I'm a student doing my masters thesis and trying to work with S-Net version 1.0 (tool used for statistical analysis and visualizations of internet traffic) that is written in R. The problem is this: I have a perl script calling a function defined in an R script that is located in a directly different from where the perl script is. This gives the following error. >>> echo

From: Jiri Pirko <jiri at nvidia.com> Virtio spec introduced a feature VIRTIO_NET_F_GUEST_HDRLEN which when set implicates that the driver provides the exact size of the header. Quoting the original virtio spec: "hdr_len is a hint to the device as to how much of the header needs to be kept to copy into each packet" "a hint" might not be clear for the reader what does

When the Virtio queue is full, a work item is scheduled to execute in 1ms that retries adding the request to the queue. This is a large amount of time on the scale on which a virtio-fs device can operate. When using a DPU this is around 40us baseline without going to a remote server (4k, QD=1). This patch queues requests when the Virtio queue is full, and when a completed request is taken off,

Hi all. I have an issue with T.38 and re-invites. Topology: provider -> A (asterisk 1.6) -> B (asterisk 1.6) -> extension -> -> (software fax, gateway whatever). When between A and B trunk is canreinvite=no everything is working smooth. When I switch canreinvite to yes, it stop working. Do you have any idea where the issue can be? Any help will be much appreciated. Marek Soha
