Description

Please vote Yes if you agree with all of the following. If you disagree, please vote No. If you don't have an opinion, please vote Abstain. I move that: The TC agrees to resolve the following specification issue: Issue #104: virtio-net: define USO feature -------------------------------------- There is a USO (UDP Segmentation offload) feature that is going to be a requirement of Windows for server-grade network adapters. It is different from existing UFO: - UFO fragments the UDP packet and only first fragment carries the UDP header (SKB_GSO_UDP in the Linux network stack) - USO segments the UDP packet, each segment has a UDP header and IP identification field is incremented for each segment. It is designated as SKB_GSO_UDP_L4 in the Linux network stack but not supported by virtio-net The host USO feature is to be defined for virtio-net. -------------------------------------- The TC accepts the following proposed changes to the specification: -------------------------------------- https://lists.oasis-open.org/archives/virtio-comment/202104/msg00024.html -------------------------------------- The TC agrees to include the above change(s) in specification version(s) "virtio-v1.2-cs01", and future versions of the specification. -------------------------------------- Reminder: A Voting Member must be active in a TC to maintain voting rights. As the Virtio TC has adopted a standing rule to conduct business only by electronic ballot, without Meetings, a Voting Member who fails to cast a ballot in two consecutive Work Product Ballots loses his or her voting rights at the close of the second ballot missed. --------------------------------------
