Hello,

I'm trying to get my ConnectX5 NIC working with DPDK v21.11 but I'm
wondering if the card I have simply isn't compatible. I first noticed that
the model I was given is MCX515A-CCA_Ax_Bx. Below are some of the error
logs when running dpdk-pdump.

I noticed that the pci id of the card I was given is 15b3:1017 as below.
This sort of indicates to me that the PMD driver isn't supported on this
card.

af:00.0 Ethernet controller [0200]: Mellanox Technologies MT27800 Family
[ConnectX-5] [15b3:1017]

I'd appreciate it if someone has gotten this card to work with DPDK to
point me in the right direction or if my suspicions were correct that this
card doesn't work with the PMD.

Best,
Aaron
