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

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:

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(http://doc.dpdk.org/guides/nics/mlx4.html#supported-nics)
2. For ConnectX-3*, ConnectX-4*, if official dpdks only support ethernet
adapter but not infiniband adapter version?
Thanks,
Quan
