From: David Spinadel <david.spina...@intel.com> Currently EBS status in scan complete notifications is set to success if EBS wasn't activated. FW will add a special return value for cases when EBS wasn't activated and we add a print of this status.
This change is needed for debug only, no behavior changes.
