Bug ID: 590
Summary: Transmit errors with i40e VF using SR-IOV on a vSphere
VM
Product: DPDK
Version: 20.11
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: christopher.swin...@metaswitch.com
Target Milestone: ---
Overview:
I am trying to make use of DPDK with an XXV710 VF using SR-IOV on a vSphere VM,
however I am finding that with DPDK 20.11 that I am unable to transmit any
packets in my application. When running testpmd I find that there are no
packets transmitted and the tx-error stat just keeps getting incremented when a
packet is transmitted.
I did some further testing of different DPDK versions and found that the
following commit is the one that stopped these cards working in a vSphere VM:
https://github.com/DPDK/dpdk/commit/34283fc94847f237677edd5909639503c605daeb
When I revert this commit I find that i40e VFs on vSphere do work with DPDK
20.11.
Steps to Reproduce:
This can be reproduced with the following steps:
- Add an XXV710 VF SR-IOV interface to a vSphere VM
- Use testpmd to transmit packets on the vSphere VM (I used `testpmd -l 2,4,6
-- --stats-period=5 --forward-mode=mac --port-topology=loop`)
Actual Results:
The tx-error stats are incremented and no packets are transmitted.
Expected Results:
The packets should be transmitted.
