HI Quan, Your NIC is configured to use InfiniBand protocol. InfiniBand is not supported with DPDK , we have it in plans but not with ConnectX-3.
Try to change it to ETH and check if works. In general we recommend to use ConnectX-3 Pro at least. Please follow instructions from dpdk.org documentation: http://doc.dpdk.org/guides/linux_gsg/linux_drivers.html#bifurcated-driver http://doc.dpdk.org/guides/nics/mlx4.html Best Regards, Olga -----Original Message----- From: users [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, October 31, 2018 7:19 PM To: [email protected] Subject: [dpdk-users] Bring DPDK on ConnectX-3 Hi， Recently I have worked on running dpdk on our infiniband card but failed. Our adapters card is ConnectX-3, which is in the dpdk’s support hardwares list, but specific type, MSX6710-FS2F2 is not found in detailed support nics list of mlx4. Environment Adapter card: Mellanox MSX6710-FS2F2 ConnectX-3 CentOS version: CentOS Linux release 7.5.1804 (Core) Linux version: Linux version 3.10.0-862.11.6.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) ) Ibstat: CA 'mlx4_0' CA type: MT4099 Number of ports: 1 Firmware version: 2.42.5000 Hardware version: 1 Node GUID: 0xec0d9a0300b35fd0 System image GUID: 0xec0d9a0300b35fd3 Port 1: State: Active Physical state: LinkUp Rate: 56 Base lid: 17 LMC: 0 SM lid: 19 Capability mask: 0x0251486a Port GUID: 0xec0d9a0300b35fd1 Link layer: InfiniBand Quesion Description I tried several versions of dpdk on our infiniband, and got different errors. Dpdk-2.0.0: 1. Run tools/dpdk_nic_band.py, there is no ConnectX-3 in output. 2. Running hellowolrd is ok. 3. Running l2fwd is failed. ./build/l2fwd -l 0-3 -n 4 -- -q 8 -p ffff Initializing port 0...

Running helloworld is failed ./build/helloworld -c f -n 4 EAL: Error - exiting with code: 1 Cause: Requested device 0000:82:00.0 cannot be used Now I wonder : 1. If official dpdks only support the one nic of mlx4 listed in official guide(https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdoc.dpdk.org%2Fguides%2Fnics%2Fmlx4.html%23supported-nics&data=02%7C01%7Colgas%40mellanox.com%7Cf4bd25df07b847f0388508d63f54f3c3%7Ca652971c7d2e4d9ba6a4d149256f461b%7C0%7C0%7C636766031463109970&sdata=9cUNXtUPjxfg0CMm0IAyOoh0WvvHLzO0SW%2BAwzvltuM%3D&reserved=0) 2. For ConnectX-3*, ConnectX-4*, if official dpdks only support ethernet adapter but not infiniband adapter version? Thanks, Quan
