Hello, I have a ConnectX-4 dual-100Gbps NIC that works with DPDK versions 24.03 and 24.07 but not with 24.11 or 25.03.
0000:04:00.0 'MT27700 Family [ConnectX-4] 1013' numa_node=0 if=enp4s0f0np0 drv=mlx5_core unused=vfio-pci 0000:04:00.1 'MT27700 Family [ConnectX-4] 1013' numa_node=0 if=enp4s0f1np1 drv=mlx5_core unused=vfio-pci Setting the log levels to debug, the newer versions are unable to configure more than one (1) description on any queue: ETHDEV: Invalid value for nb_tx_desc(=1024), should be: <= 1, >= 0, and a product of 1 Whereas using the older version, I am able to set a larger number of descriptors. Tried 512, 1024, 2048 and 4096. ********************* Infos for port 0 ********************* MAC address: EC:0D:9A:35:1A:16 Device name: 04:00.0 Driver name: mlx5_pci Firmware-version: 12.24.1000 Devargs: Connect to socket: 0 memory allocation on the socket: 0 Link status: up Link speed: 100 Gbps Link duplex: full-duplex Autoneg status: On MTU: 2030 Promiscuous mode: enabled Allmulticast mode: disabled Maximum number of MAC addresses: 128 Maximum number of MAC addresses of hash filtering: 0 VLAN offload: strip off, filter off, extend off, qinq strip off Hash key size in bytes: 40 Redirection table size: 4 Supported RSS offload flow types: ipv4 ipv4-frag ipv4-tcp ipv4-udp ipv4-other ipv6 ipv6-frag ipv6-tcp ipv6-udp ipv6-other ipv6-ex ipv6-tcp-ex ipv6-udp-ex esp l4-dst-only l4-src-only l3-dst-only l3-src-only Minimum size of RX buffer: 32 Maximum configurable length of RX packet: 65536 Maximum configurable size of LRO aggregated packet: 65280 Current number of RX queues: 4 Max possible RX queues: 1024 Max possible number of RXDs per queue: 65535 Min possible number of RXDs per queue: 0 RXDs number alignment: 1 Current number of TX queues: 4 Max possible TX queues: 1024 Max possible number of TXDs per queue: 65535 Min possible number of TXDs per queue: 0 TXDs number alignment: 1 Max segment number per packet: 40 Max segment number per MTU/TSO: 40 Device capabilities: 0x10( FLOW_SHARED_OBJECT_KEEP ) Switch name: 04:00.0 Switch domain Id: 0 Switch Port Id: 65535 Device error handling mode: none Device private info: none Is this a known issue?
