[dpdk-users] IP_PIPELINE DPDK

[Zhang, Roy Fan]

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 at dpdk.org<mailto:user at 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.

EAL: Support maximum 128 logical core(s) by configuration.

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
