    Add alternative command to disable lldp agent for i40e devices

    LLDP information is not available for certain i40e network devices when
    running system host-lldp-neighbor-show.

    This is caused by the firmware lldp agent on the devices not getting
    disabled by the i40e-lldp-configure.sh script which is invoked by lldpd.

    The command used to disable the firmware lldp agent in the script works
    for some firmware versions found on devices, but not others. This change
    adds an ethtool command to disable the lldp agent which works for these
    other firmware versions.

    From testing, the ethtool method is used for firmware versions 5.05 and
    8.10. The sysfs method is used for firmware version 7.10. In all cases,
    the driver version is 2.14.13
