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

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 (builder at kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) )

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... PMD:librte_pmd_mlx4: 0x951960: TX queues number update: 0 -> 1
PMD: librte_pmd_mlx4: 0x951960: RX queues number update: 0 -> 1
PMD: librte_pmd_mlx4: 0x951960: QP state to IBV_QPS_INIT failed: Invalid arguments
EAL: Error - exiting with code: 1
Cause: rte_eth_rx_queue_setup:err=-22, port=0
Dpdk-16.07.2(next version of dpdk-2.0.0)
1. Run tools/dpdk_nic_band.py, and it prints ConnectX-3
2. 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
