Thank you for your reply, Thomas!

This is the port summary.

Number of available ports: 4
Port MAC Address       Name         Driver         Status   Link
0    00:07:43:5D:4E:60 0000:05:00.4 net_cxgbe      down     100 Gbps
1    00:07:43:5D:4E:68 0000:05:00.4_1 net_cxgbe      down     100 Gbps
2    00:07:43:5D:51:00 0000:0b:00.4 net_cxgbe      down     100 Gbps
