![]() When qeth device is queried for ethtool data, hardware operation is performed to extract the necessary information from the card. If the card is not online at the moment (e.g. it is undergoing recovery), this operation produces undesired effects like temporarily freezing the system. This patch prevents execution of the hardware query operation when the card is not online. In such case, ioctl() operation returns error with errno ENODEV.
