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"

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.
