[dpdk-dev] Cannot use MLX4 with igb_uio driver

[Royce Niu]

Dear all,

I cannot use my Mellanox 3 Pro, after I binded it with igb_uio driver.

It always shows when I use my DPDK application.

EAL: Detected 32 lcore(s)
EAL: Probing VFIO support...
PMD: bnxt_rte_pmd_init() called for (null)
EAL: PCI device 0000:02:00.0 on NUMA socket 0

PMD: librte_pmd_mlx4: cannot access device, is mlx4_ib loaded?
EAL: Error - exiting with code: 1
  Cause: Cannot create mbuf pool

---------------
I have added CONFIG_RTE_LIBRTE_MLX4_PMD=y in .config, and
install MLNX_OFED_LINUX-3.4-2.0.0.0.

Thanks.
