&nbsp; &nbsp; hi£¬i'm so sorry to disturb, but i got a question which stuck me for a long time.
when dpdk-process is running, assuming that dpdk use a NIC named eth0, and eth0 insmod a i40e drivers before, then when i offload the NIC from igb_uio/vfio_pci to i40e, and stop the dpdk-process . my server machine will shutdown.
&nbsp;&nbsp;&nbsp; i wonder how can i stop this happen?&nbsp;&nbsp; looking forward to your reply! thank you very much

best regards
