Hi Qiming, Thanks for your information. From the log of i226V, you can see that the string "Requested device 0000:03:00.0 cannot be used" appeared at init 03:00.0. Then its execution stopped at "EAL: Probe PCI driver: net_igc (8086:125c) device: 0000:06:00.0 (socket 0)" with no subsequent action.
If the device can be executed normally, the complete message should be like the i211_log attached, right?

But for i226v's log, I don't see any issue, seems 06:00.0 init success. Could you clarify it?
