Firmware version 0.0.0 has a special meaning and just means that we could not parse the product information string. In such case, do nothing (i.e. leave the .fw_version string empty). Signed-off-by: Vincent Mailhol --- *N.B.* Drivers had to also fill ethtool_drvinfo::driver and ethtool_drvinfo::bus_info.
