Log display: i40e 0000:5e:00.0: Reset VF 30 never finished

[MacYoung]

Hi,

We have x710 dual port NIC with following details

5e:00.0 Ethernet controller: Intel Corporation Ethernet Controller X710 for 10GbE SFP+ (rev 02)
5e:00.1 Ethernet controller: Intel Corporation Ethernet Controller X710 for 10GbE SFP+ (rev 02)

Environment:

i40e driver version : 2.22.18

centos kernal version : 3.10.0.957.1.1

When VF is assigned to a VM, the following information is always displayed:

1.  i40e  0000:5e:00.0: Reset VF 30 never finished

2. PTP external clock not supported

I wonder what might have caused it. 

Appreciate any help on this.

Hi MacYoung,

Thank you for posting in Intel Ethernet Communities.

Regarding i40e 0000:5e:00.0: Reset VF 30 never finished, we would be grateful if you could give some information as per below:

• Are you able to test with different version of driver and OS? e.g. lower version of i40e/CentOS version 8/RHEL 9.1. Since CentOS are not listed under supported Operating Systems as per below Release Notes document link (page 6): https://downloadmirror.intel.com/772070/Release_Notes_28.0_rev_1.1.pdf
• i40e 0000:5e:00.0: Reset VF 30 never finished shows that it happen on 5e:00.0 port. Does this happen on other 5e:00.1 port also?
• What is your network switch model? e.g. Juniper/Cisco

You may also utilize Linux lsmod utility to confirm that i40evf driver for the VF has loaded successfully as per below document link (page 20):

PTP external clock not supported might be showing due to HW limitation, the 710 do not support PTPv2.1 as per below article link:
