=====================================================================
General Discussion
* DPDK Summit will be May 8-9 in Prague:
https://www.dpdk.org/event/dpdk-summit-2025-prague/
* git apply patch fails for next-dts
   * Cody Cheng who works on UNH CI Testing can resolve this.
   * 1. Verify
https://git.dpdk.org/tools/dpdk-ci/tree/tools/pw_maintainers_cli.py
requires no updates for next-dts
   * 2. Add next-dts to the branches dict in
https://git.dpdk.org/tools/dpdk-ci/tree/tools/create_series_artifact.py
   * 3. Submit to ci@dpdk.org for review.
* Failing existing tests due to scapy
   * Luca observed DTS failing due to errors at packet creation. This may
be due to updating Scapy, which may have brought in a small API change.
      * Nick from the UNH team should try to recreate this, share output on
the dts-dev slack to sync with the ARM guys and confirm it is the same,
* Reviews are more important than new patches right now - we still have a
backlog which we need to review and merge to our next branch.
* DTS Single node Deployments:
   * By running TG and DUT as one system, this reduces the burden for
developers to run DTS using only 1 board. This probably reduces no
limitations for functional tests.
   * Scapy asyncsniffer will never init condition properly when running on
a single system
   * Patrick to make ticket so we can start tracking what the issues are
* DTS internal API:
   * Paul was trying to write docs for the DTS “user” (test developer).
   * What should be exposed to the developer for testsuite
      * Testsuite class should be exposed
      * Logger, for instance, should not directly be used (leveraged only
by framework), but it is located at the same path as TestSuite.
      * Create a top level dir for all the modules that users should use
directly.
      * Seconded by Ian, who ran into this as a new user who did not know
which
   * Currently we have no restrictions on DTS API updates during regular
release dev cycles.

=====================================================================
Patch discussions
* Patchseries merged this week:
   * Dynamic config testsuite
   * fix pass rate edge case in results json
   * Hello_world
   * unified  packet testsuite
      * Is it 1:1 with legacy DTS? If so, copyrights should be brought over.
      * Is nvgre deprecated in DPDK? This was removed in the new testsuite.
* Queue Start Stop was updated this week to change how deferred start is
validated (now checks both that port doesn’t start erroneously, and that it
can be updated at runtime
   * Patrick needs to run this and merge it, but he has no more comments
* Jumboframes/mtu_update
   * Initial testcases simply bring up testpmd using –max-pkt-len
(includinig jumboframe MTU), and send packets
   * Final testcases bring up testpmd, update MTU at runtime, send packets
   * CC Ian Stokes on this who has some background in this subject
* Port topology patch:
   * Luca has offered to take this off of Nick’s hands
   * Ian should be CC’d on this
