Hi
when I use dpdk to call rte_eth_tx_burst function for sending data from the secondary process, vfio will crash:




PID: 60699 TASK: ffff8f0152235df00 CPU: 14  COMMAND: "testlstack02"

#13 [ffffa7d8ceec3f50] page_fault at ffffffff90e012de




The crash occurs when the secondary queue of the secondary process send pkts. I have tested that the primary process and the first queue of the secondary process do not crash. I use i40e X710 nic.




Has anyone ever encountered simlilar issue? please provide some ideas for fixing the issue.

Thanks!
