This is live document to be updated in coming time and work towards it for its design which can result in a draft specification. The objectives are: 1. to consider these requirements in introducing new features listed in the document and otherwise and work towards the interface design followed by drafting the specification changes. 2. Define practical list of requirements that can be achieved in 1.4 timeframe incrementally and also have the ability to implement them. Please review. TODO: 1. Some more refinement needed for rx low latency and header data split requirements. --- changelog: v1->v2: - major update of receive flow filter requirements updated based on last two design discussions in community and offline research - examples added - link to use case and design goal added - control and operation side requirements split - more verbose v0->v1: - addressed comments from Heng Li - addressed few (not all) comments from Michael - per patch changelog Parav Pandit (7): net-features: Add requirements document for release 1.4 net-features: Add low latency transmit queue requirements net-features: Add low latency receive queue requirements net-features: Add notification coalescing requirements net-features: Add n-tuple receive flow filters requirements net-features: Add packet timestamp requirements net-features: Add header data split requirements net-workstream/features-1.4.md | 308 +++++++++++++++++++++++++++++++++ 1 file changed, 308 insertions(+) create mode 100644 net-workstream/features-1.4.md -- 2.26.2 This publicly archived list offers a means to provide input to the OASIS Virtual I/O Device (VIRTIO) TC.
