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 work towards the interface design followed by drafting the specification changes. 2. Define list of requirements that can be practical to achieve in 1.4 timeframe incrementally and also have the ability to implement them. Please review mainly patch 5 at the priority. Receive flow filters is the first item apart from counters to complete in this iteration to start drafting the design spec. Rest of the requirements are largly untouched other than Stefan's comment. TODO: 1. Some more refinement needed for rx low latency and header data split requirements. changelog: v4->v5: - Refined receive flow filter requirements to be ready for spec draft - updated timestamp requirement to feedback from Willem - Fixed counters rquirements on comments from David v3->v4: - receive flow filters requirements undergo major updates to take to spec draft level. - Addressed comments from Xuan, Heng, David, Satananda. - Refined wordings in rest of the requirements v2->v3: - addressed comments from Stefan for tx low latency and notification - redrafted the requirements to use rearm term and avoid queue enable confusion for notification - addressed all comments and refined receive flow filters requirements to take to design level 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 | 383 +++++++++++++++++++++++++++++++++ 1 file changed, 383 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.
