From: Lior David <liord@xxxxxxxxxxxxxx> There are special kinds of FW such as WMI only which are used for testing, diagnostics and other specific scenario. Such FW is loaded during driver probe and the driver disallows enabling any network interface, to avoid operational issues. In many cases it is used to debug early versions of FW with new features, which sometimes fail on startup. Currently when such FW fails to load (for example, because of init failure), the driver probe would fail and shutdown the device making it difficult to debug the early failure. To fix this, ignore load failures in WMI only FW and allow driver probe to succeed, making it possible to continue and debug the FW load failure.
