Re: [dpdk-users] Failed to initialize one specific port of X710-DA4 in i40e pmd

Hi Aaron, Masutani-san, all,

We are also facing this issue in one of the setups. If you were able to get to the bottom of this issue, can you please let us know the cause and the solution.

Thanks,
Ananda

Does anyone know what tool can be used to configure/view the settings for the XL710?  I would like to view the DCB and TC settings.  Based on the i40e README you can't use dcbtool and I don't see anyway to do it with ethtool.  One of the ports on the XL710 is working for me but the other one is showing the error about the TC map.

I see this message from the kernel's i40e driver for the port that isn't working with DPDK:
Non-contiguous TC - Disabling DCB
