V2 - Add UDP protocol support - Add VXLAN protocol support - Removed gen/packet telemetry function as it was unimplemented - Fixed IPv4 endianness issue
As I am coming to the end of my internship I will now longer be working on this project. As discussed on the thread [1] this patchset will be marked non-applicable on patchwork. We are posting the V2 here to make the rework publicly available. - Ronan [1] DPDK Mailing list discussion around Gen library upstreaming; http://mails.dpdk.org/archives/dev/2022-January/232845.html This patchset introduces a Gen library for DPDK. This library provides an easy way to generate traffic in order to test software based network components. This library enables the basic functionality required in the traffic generator. This includes: raw data setting, packet Tx and Rx, creation and destruction of a Gen instance and various types of data parsing. This functionality is implemented in "lib/gen/rte_gen.c". IPv4 parsing functionality is also added in "lib/net/rte_ip.c", this is then used in the gen library. A sample app is included in "examples/generator" which shows the use of the gen library in making a traffic generator. This can be used to generate traffic by running the dpdk-generator generator executable. This sample app supports runtime stats reporting (/gen/stats) and line rate limiting (/gen/mpps,<target traffic rate in mpps>) through telemetry.py. As more features are added to the gen library, the sample application will become more powerful through the "/gen/packet" string parameter (currently supports IP and Ether address setting). This will allow every application to generate more complex traffic types in the future without changing API.
