Cause

This occurs due to driver version mismatch  that are loaded other than qfle3.

Resolution

• Upgrade or Install the below version qfle3 drivers to fix the issue  

qfle3-1.0.86.0

     qfle3i_1.0.23.0
     qfle3f_1.0.68.0
     qcnic_1.0.26.0

• Reboot the host for the upgrade to be successful 

       
For ESXi 6.7 go to Customer Connect
For ESXi 6.5 go to Customer Connect 

Workaround:
To workaround this issue disable qfle3i,qfle3f and qcnic. Use the following command and reboot the ESXi host.
esxcfg-module -d qfle3i
esxcfg-module -d qfle3f
esxcfg-module -d qcnic

This will load only qfle3 driver.
