To Reproduce Steps to reproduce the behavior:
In the process of verifying OSPRH-14132 where os-net-config executes 2 times (one for first deployment and one for update), I have seen the following errors in logs

However, this files exists, so I think it is a race condition
[root@compute-1 tripleo-admin]# ls /sys/class/net/enp4s0f1np1/device/sriov_drivers_autoprobe /sys/class/net/enp4s0f1np1/device/sriov_drivers_autoprobe [root@compute-1 tripleo-admin]# ls /sys/class/net/enp6s0f3/device/sriov_drivers_autoprobe /sys/class/net/enp6s0f3/device/sriov_drivers_autoprobe
Regression passed, so I think it is only a logging issue.
Expected behavior
- Errors should not be in os-net-config log
Bug impact
- Only errors in logs
