There are special kinds of FW such as WMI only which
are used for testing, diagnostics and other specific
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.
