Hi Amir - please test. Marking verification done for now. Regression consequence is limited to the DPDK use case.

Done testpmd> two lines indicates errors in counter offset supports detection. [Fix] the issue is fixed with the following upstream commit from v5.5-rc1 which cleanly applied above focal. 208d70f562e5 IB/mlx5: Support flow counters offset for bulk counters Our QA-dpdk team tested the focal kernel with this patch and found no issues. [regression potential] function mlx5_ib devx _is_flow_counter (from the devx interface) signature has changed so anything that uses it like rdma-core might be impacted.
