Hello,

I need help to manage packet using dpdk under xeon intel chip. When I launch testpmd, I'm wondering if output traces below are blocking to check bandwith:

EAL: Detected 8 lcore(s)
EAL: 1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size
EAL: Probing VFIO support...

Port 0 Link Up - speed 0 Mbps - full-duplex Port 1 Link Up - speed 0 Mbps - full-duplex

On one side, traces show that there is NUMA, speed and hupepage issue. Have you a idea ?

Thank you
