Minutes

=====================================================================
General Discussion
* Nick Pratte from UNH-IOL is doing an internship outside IOL this Summer,
so he will not be working on DTS as much as expected
   * He still wants to submit some testsuites this Summer, but all his
framework side work (like perf tg (trex) support) will go to Patrick or Dean
   * He may be back to working on DTS more regularly at the end of the
Summer that is TBD
* CI Lab items:
   * We’re still debugging some of the failures that we saw on the cx5
before DPDK Summit, which took that testing offline in our public reporting
system
   * Dean is adding some new NICs to the public testing
      * Broadcom 25g
      * Broadcom 100g (p2100g)

=====================================================================
Patch discussions
* Rte_flow: https://patchwork.dpdk.org/project/dpdk/list/?series=35269
   * Dean has updated the flow testsuite, adding a flow validate step
   * If flow validate fails, skip the testsuite
   * If flow validate passes, then flow create fails, fail the testsuite
   * If flow validate passes, flow create passes, then run the testsuite
and validate the flow behavior (pass or fail based on testsuite assert)
   * Dean added a verify_skip method to the testsuite class used for
skipping testsuites at runtime based on some condition
* Per test suite config docs:
https://patchwork.dpdk.org/project/dpdk/list/?series=35240
   * Doc update towards explaining how to leverage the per test suite config
* Perf tg support:
https://patchwork.dpdk.org/project/dpdk/list/?series=35239
   * Patrick is picking up this series
   * UNH people will ensure that the forwarding test metrics align with the
results we get from legacy DTS, which is considered stable
   * The legacy framework single core forwarding test had some effort done
towards supporting different traffic mixes/profiles, and we should examine
this for the new testsuite, but the MVP will feature basically a uniform
set of packets
* L4 packet matching:
https://patchwork.dpdk.org/project/dpdk/list/?series=3522
   * Luca provided a few nits
   * Nits are resolved, so Patrick can test and merge
* Improved port handling:
https://patchwork.dpdk.org/project/dpdk/patch/20250506131657.1576152-1-luca.vizzarro@arm.com/
   * Patrick needs to review ASAP
