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

[Aaron Hughes]

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
