When starting up the interface in DPDK the mlx5_ctrl_flow function returns -12. With OFED version 5.3-18.104.22.168it does work. Any idea what could be the issue ? Was there any breaking change in 5.4-1.0.3 ?
Ubuntu 20.04 kernel 5.4.0-84
NIC Connect X5
firmware-version: 16.32.1010 (MT_0000000008)
Using DPDK 17.11.04.
Thank you for posting your query on our community. There are no known issues with DPDK 17.11 and Mellanox OFED 5.4-1.0.3 at the moment.
- Please ensure that DPDK 17.11 is installed properly on your system - https://doc.dpdk.org/guides/linux_gsg/build_dpdk.html
- Please note that the Mellanox OFED installer script will have to be run with the following flags: ./mlnxofedinstall --dpdk
- mlx5 library is set by enabling CONFIG_RTE_LIBRTE_MLX5_PMD=y in the DPDK configuration file prior to the DPDK compilation
The error code “-12” returned by the mlx5_ctrl_flow function in DPDK usually indicates an invalid argument. We will need more information to debug this issue further. If the issue still persists, I suggest you to collect a sysinfo-snapshot and open a support case for further investigation of the issue. The support ticket can be opened by emailing "Networkingfirstname.lastname@example.org "
Please note that an active support contract would be required for the same. If you do not have a current support contract, please reach out to our Contracts team at email@example.com
