General Discussion
* DPDK 25.03 has been released
* We are aggregating the patches/tickets for the 25.07 DTS roadmap. Initial
proposals are:
   * 1. TG abstraction rework (to facilitate performance TGs), testsuite
API additions for perf workloads, and TREX class implementation
      * Luca raised that it may be best to leave the perf TGs as child
classes of the current tg abstract class and simply not implement the
capturing methods
      * Luca also raises that his asyncsniffer patchseries adds some new
methods of collecting packets, such as collecting until a stop condition is
met (like seeing packet X). This may split out packet send and packet
capture from send_packet_and_capture(), making them independent.
   * 2. Write testsuite perf_single_core_fwd
   * 3. Write testsuite rte_flow
   * 4. Port VF support
   * 5. Docs improvements for new users
      * Luca has indicated that Thomas Wilks will contribute to this
   * 6. Smoke test tweaks to ensure they are not a setup burden
   * 7. Rework packet send and receive functions in the Testsuite API
towards supporting IP networking in an L3 environment
   * 8. DPDK Testsuite API: This will provide a stable API which will not
be broken going forward (except at agreed upon intervals)
   * 9. RSS Support Testsuites
      * Work for this is basically done - reviews needed though:
https://patchwork.dpdk.org/project/dpdk/list/?series=3D34713
   * 10. Non-Development roadmap goals include: Filming a video series
explaining DTS usage, scheduling syncs with testers/developers from DPDK
member companies to introduce them to DTS.
   * 11. Update TestResult module in order to give a more human readable
summary of the testsuites
   * 12. Improved interactive shell data collection and logging.
      * Add a file which exclusively logs the shell interactions
   * 13. Add dedicated file manager to handle passing files and artifacts
between the test engine and nodes in a path agnostic manner
      * This will be a component of the new DPDK DTS API
   * 14. Flexible port binding
      * Give the opportunity to test suites to use all or part of the
supplied port topology with the kernel drivers (instead of DPDK). Could be
achieved with a decorator
      * This will require the Topology class to be aware of what=E2=80=99s =
truly
available for DPDK and provide only the right ports for it
   * Move these over to:
https://docs.google.com/document/d/1doTZOOpkv4D5P2w6K7fEJpa_CjzrlMl3mCeDBWt=
xnko/edit?tab=3Dt.0
* This is a friendly reminder that when you start working on a testsuite,
you should make sure there is a ticket documenting that on DPDK/DTS bugzill=
a
* Smoke tests do not run from next-dts currently, due to a patch from the
per-test-suites-configuration patch from the end of 25.03.
   * Patrick will submit a fix
   * Also, it is worth discussing the usefulness of the smoke tests
generally:
      * Some tests are confirming simple setup correctness and help
validate DTS has been configured right, while others are testing DPDK more
broadly (like the dpdk-test runs) and may pose a burden to developers
         * One option is to keep the smoke tests as they are but default
them to off instead of on
