> Subject: [PATCH v3 0/3] Support UDP/IPv4 GSO
>
> With the support of UDP Fragmentation Offload (UFO) and TCP Segmentation
> Offload (TSO) in virtio, VMs can exchange large UDP and TCP packets
> exceeding MTU between each other, which can greatly reduce per-packet
> processing overheads.
>
> When the destination of the large TCP and UDP packets is crossing
> machines, the host application needs to call two different libraries,
> GSO and IP fragmentation, to split the large packets respectively.
> However,the GSO and IP fragmentation library have quite different APIs,
> which greatly complicates the host application implementation.
>
> To simplify application development, we propose to support UDP/IPv4
> fragmentation in the GSO library. With supporting UDP GSO, host
> applicationss can use the unified APIs to split large UDP and TCP packets.
>
> This patchset is to support UDP/IPv4 GSO. The first patch is to provide
> UDP GSO function, the second patch is to enable UDP/IPv4 GSO in the
> testpmd checksum forwarding engine, and the last patch is to update the
> programmer guide and testpmd user guide.
>
> Change log
> ==========
> v3:
> - replace rte_pktmbuf_mtod() with rte_pktmbuf_mtod_offset().
> - fix meson build.
> - add updates to document for better explaining how UDP GSO works.
> V2:
> - fix fragment offset calculation bug.
> - add UDP GSO description in testpmd user guide.
> - shorten the second patch name.
