And it didn't work I assume? From what I am seeing, those ports are supported by DPDK (8086:1F41),
as they are recognized by it, so that should not be the problem. Can you run testpmd and send a few packets to them?
Then use, "show port stats all" and see the statistics are updated (make sure that you send valid packets :))

BR,
Pablo
