Hi,
"tx frame not ready"? means VPP didn't find empty queue at linux side. Linux is processing too slow which results in that behavior and VPP drops those packets. While when you use dpdk, you bypass linux kernel (bottleneck), so you don't find such behavior. If you still want to use the virtual interfaces for some reason. It would be preferable to use tapv2.

After i used iperf to send 400Mb/s 64B packets,the iperf server did not show the received bandwidth. So i inputed show error,the result showed many packets were not handled normally because of tx frame not ready. when i used dpdk+VPP to run the same case,this phenomenon did not appear. i hope someone could give me some guidance. thank you.[cid:attach_0_1520B96F4282B646_19234@lists.fd.io]
