HI Benoi:
Thanks for your reply.
I have done the gdb test to track af_xdp_create_queue() function. Acutlly the
af_xdp_create_queue() return error value, The function call flow is as below, I
doubt that Linux kernel version 5.4 doesn't support af_xdp fucntion for virtio

Hi Stanislav,
Thank you very much for your response. I suppose then that "Vectors/Call" <=>
"Packet/Call" <=> "Packets/Vector" ?
I'm sory if what I'm asking for is pretty obvious, I'm just not familiar with
some of the concepts displayed with "show runtime"
Thanks again.

Your understanding is correct.
Many of the things in VPP are low level and take a bit of getting used to.

Hi Benoit Ganne:
I have upgrade linux kernel version to 5.17.3, and then do the same test, the
test result is OK, no kernel error message occured: libbpf: Kernel error
message: virtio_net: Too few free TX rings available.
bpf.vger.kernel.org mail disccuss information also gives support for this
