Instead, use 'ret' variable and bypass it to upper callers. The remaining three patches are to introduce new firmware features -- drop and crash simulation. The first feature is to drop packets when calling flush ops with drop=1. The crash simulation is to verify if driver can handle events of abnormal conditions of firmware or hardware reported by firmware.
