Hi All, I have a weird issue with an re-branded Mellanox card (sold as HP, but MLX hardware: HP InfiniBand FDR/EN 10/40Gb Dual Port 544FLR-QSFP Adapter) which is failing to start (rte_eth_dev_start) with the following message:
. PMD: net_mlx4: 0xebbf40: cannot attach flow rules (code 95, "Operation not supported"), flow error type 2, cause 0x7f76cd22b680, message: flow rule rejected by device . I can't say what that cause means, any suggestion on how to decode those numbers? Also, I don't have configured any flow rule (or nothing related) and the very same code works fine one a ConnectX-4 Lx. I suspect a firmware compatibility issue, as the HP card is running with the FW version 2.30.3200 while apparently the Minimum firmware version required to support DPDK is 2.36.5000: http://www.mellanox.com/related-docs/prod_software/MLNX_DPDK_Quick_Start_Guide_v16.11_1.5.pdf (Page 8). The HP card is running on Mellanox firmware. Did anyone encountered a similar issue and can comment if the firmware can be the problem here? Thanks -- BR, Filip +48 666 369 823
