General Discussion
* DTS Videos: We have shared the DTS tutorial videos with Ben from Linux
Foundation / DPDK and he will cross post to their Youtube or other socials
   * Video 1: How to run DTS
   * Video 2: How to write a DTS testsuite

Patch discussions
* TG Driver Bind:
   * Andrew submitted a new version with a new =E2=80=9Cbound for kernel=E2=
=80=9D property
   * Patrick Robbto review and merge
* RSS:
   * Paul has submitted an updated version
   * Patrick Robb to test this and review/merge
* Mbuf fast release testcase / tx_offload:
   * Need to ensure that tx offload can only be applied to tx port/queue
instead of rx or tx.
   * Need to ensure we are correctly delineating between the queue and port
offloads config
* Virtio:
   * V1 is finished but Dean is sick so it won=E2=80=99t be sent until next=
 week
* DTS API:
   * Paul has sent the V1
   * Goal: every import for a testsuite is from the api dir
   * Patrick Robb to do a review
   * UNH guys should make a =E2=80=9Cdepends-on=E2=80=9D patch for this
      * Packet_capture imports cpu logical core list
      * We need to go through each testsuites and see what it imports and
see if it can be moved out
      * Let=E2=80=99s just make a spreadsheet with a row per import and col=
or code
by status, assign testsuites to people etc.
      * Patrick Robb to ticket this
      * Paul will handle artifact, and the parts inside a testsuite
* Single_core_fwd:
   * Now, in config func_traffic_generator does not include a TG path and
config path, since it is not needed, only perf_traffic_generator does
   * Now, context stores 2 traffic generators, which can be optionally a TG
or None based on whether they=E2=80=99re specified in the config
   * Trying to bind to the correct driver on TG at test_run state machine=
=E2=80=99s
testcasesetup:
      * Patrick will propose a couple ideas when he sends the next patch
      * One solution may be to gather the functional cases at runtime, run
those first, then run the perf cases second
* A couple patches have been merged:
   * Missing type hints
   * File artifact manager
* Default link topology series:
   * This breaks the DPDK build, and the UNH team needs to figure out why
* Updating docstrings:
https://patchwork.dpdk.org/project/dpdk/patch/20250910194259.1027220-2-paul=
.szczepanek@arm.com/
   * Patrick Robbshould merge this today before it goes out of date
