hi, i used VPP+afsocket to run ip4 forward case between pcA and pcB. 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.
