We were using DPDK 19 and upgraded to DPDK 21 with XL710 card on ESXi. The VF driver changed from “i40evf” to “iavf”.

We are seeing a drop of around 75% in throughput.

ESXi Version:

[root@localhost:~] esxcli system version get

   Product: VMware ESXi

   Version: 7.0.1

   Build: Releasebuild-17551050

   Update: 1

   Patch: 30

I40en Version:

 Driver Info:

         Bus Info: 0000:d8:00:0

         Driver: i40en

         Firmware Version: 6.80 0x800042e3 0.385.97


Is there any minimum required version for ESXi and i40en for DPDK 21.11 (iavf) to work?

Also, IAVF per queue stats are not showing up, is this expected?
