We successfully got 8086-1583 working with i40e 1.3.38 and 4.42 nvm.
Later we managed to upgrade from to i40e 1.3.39.1 and 4.53 nvm.
During nvm upgrade we've got following exception with the success message at the end.
Now we are not able to bring link up with old drivers and nvmneither new ones.
If nvm downgrade passes silently upgrade throws this exception every time.
Upgrade under Windows fails too with BSOD and 0x80 NMI_HARDWARE_FAILUR
