    i40evf: make early init sequence even more robust · 906a6937
    Mitch Williams authored
    When multiple VFs attempt to initialize simultaneously, the firmware may
    delay or drop messages. Make the init code more adept at handling these
    situations by a) reinitializing the admin queue if the firmware fails to
    process a request, and b) resending a request if the PF doesn't answer.
    
    Once the request has been sent again, the PF might end up getting both
    requests and send the configuration information to the driver twice.
    This will cause the VF to complain about receiving an unexpected message
    from the PF. Since this is not fatal, reduce the warning level of the
    log messages that are generated in response to this event.
