The compiler warning is:
from .../drivers/net/ionic/ionic_dev.c:7:
.../drivers/net/ionic/ionic_if.h:202:5: note: ‘rsvd’ declared here
u8 rsvd[62];
^
This has been observed with gcc 4.8.5, newer 9+ compiler are not giving
this warning.
Warning is a reminder to the user that there are some fields in the
struct not initialized with the default value.
But the C standard clarifies that in that case the field value will be
zero and code is aware of this behavior, so no initializing to a default
value is intentional and it is safe to ignore this compiler warning.
Adding '-Wno-missing-field-initializers' compiler flag to disable the
warning.
