Re: [dpdk-users] IP_PIPELINE DPDK

["Zhang, Roy Fan" <roy.fan.zhang@intel.com>]

Dear Aswathy,

Latest DPDK 16.11 supports Mellanox MLX4 and MLX5 NICs, however the PMD driver of them was disabled by default.

You may enable them in DPDK_ROOT_PATH/config/common_base file instead of config/common_linuxapp.
Please search "CONFIG_RTE_LIBRTE_MLX4_PMD" and "CONFIG_RTE_LIBRTE_MLX5_PMD" and set their values to "y"
You then can save the file and recompile DPDK.

Unfortunately I didn't have the chance to operate a Mellanox NIC, thus there might be further steps to be done in order to use this NIC in DPDK. You may find useful information at http://www.mellanox.com/related-docs/prod_software/MLNX_DPDK_Quick_Start_Guide_v2.2_3.9.pdf, please note this guide targets DPDK 2.2 so some steps relating to DPDK may be obsolete.

In case you have further questions, please CC your next email to user@dpdk.org<mailto:user@dpdk.org> so it will appear in mailing list. It may be useful for someone else later :)

Regards,
Fan

Hi Fan,

I am working on dpdk ip_pipeline. While I was trying to run dpdk ip_pipeline on Mellanox 100G NIC ,

I am getting the following error message.

Do you know why I am getting this app_init_link error? I have tried the same application on INTEL 100G NIC. It was successful.  I followed the same steps in implementing ip_pipeline in Mellanox too. But not sure, what is causing the error.
Any help will be really appreciated.

Thanks,
Aswathy
