Test-Label: intel-Testing Test-Status: SUCCESS _Testing PASS_ DPDK git repo: dpdk-next-net-mlx commit 5c0c1a13c34aa57c6e18f9ba852a9b5807c58b72 Author: Bing Zhao Date: Fri Jun 27 11:25:02 2025 +0300 net/mlx5: fix WQE size calculation for Tx queue The txq_calc_wqebb_cnt() should be consistent with the calculation in the function mlx5_txq_devx_obj_new(). Or when the input descriptor number is 512, the WQE size will be wrongly considered to be 30 when no max_inline_data is zero in some cases. The total number of WQE will be considered as 256 and that is incorrect. Adjusting the WQE size will solve the wrong calculation when the calculated WQE size is less than 64B.
