I'm new to dpdk and using dpdk-stable-17.11.2 on docker. OS is Ubuntu 14.04 and the kernel is 3.19.0-80-generic. I've followed the dpdk-setup.sh as below and bind the igb_uio driver to my device.

I got errors when running testpmd.

What have I missed?
I changed CONFIG_RTE_LIBRTE_BNX2X_PMD=n to CONFIG_RTE_LIBRTE_BNX2X_PMD=y in the $RTE_SDK/config/common_base.

This error has solved.
