qeth: restore device features after recovery
After device recovery, only a basic set of network device features is enabled on the device. If features like checksum offloading or TSO were enabled by the user before the recovery, this results in a mismatch between the network device features, that the kernel assumes to be enabled on the device, and the features actually enabled on the device. This patch tries to restore previously set features, that require changes on the device, after the recovery of a device. In case of an error, the network device's features are changed to contain only the features that are actually turned on.
