Subject: natsemi: Allow users to disable workaround for DspCfg reset
The natsemi driver contains a workaround for broken hardware which can partially reset the chip at unpredictable times, detected by checking for spontaneous changes in the DspCfg register. The effects of the hardware bug appear to be variable and can range from minor problems like small numbers of corrupted packets to major ones such as the chip becoming non-functional. In the case of minor problems the chip reconfiguration required to work around the hardware can cause more problems than the bug itself. Since we have no way of automatically determining how badly the problem manifests on any given system provide an option in sysfs allowing users to disable the workaround at runtime and provides a module option to set the default.
