The UASP driver must support all the task management functions listed in Table 20 of UAS-r04. However, not all of them are implemented in the Target core. To remain compliant while indicate that the TMR did not go through, report RC_TMF_FAILED instead of RC_TMF_NOT_SUPPORTED and print a warning to the user.
