Hi,

I am trying to enable DPDK interrupts with the function
rte_eth_dev_rx_intr_enable with a virtual function of i40e NIC then
following segmentation fault coming when the function is called. The same
code does not give a fault when used against the virtual function of the
Intel 82599 NIC. I am using DPDK version dpdk-stable-22.11.1

Program received signal SIGSEGV, *Segmentation fault.*
0x00007fffe72bceb5 in iavf_dev_rx_queue_intr_enable () from
/usr/local/lib64/dpdk/pmds-23.0/librte_net_iavf.so.23.0

Is there a known issue around this in DPDK ?

Thanks & Regards,
