The Linux UASP gadget driver is incomplete and remained broken for a long time. It was not implemented for performance either. This series adds some of the required features for the UASP driver to work. It also makes some fixes to the target core. Please note that the f_tcm is far from a good state. It needs better error recovery, error reports, more cleanup, and the ability to handle various required commands. Also please note that I try to juggle between checkpatch warnings and code style consistency. As a result, there maybe some minor checkpatch warnings. Hopefully this can help jumpstart the UASP driver. Please test it out. This was tested against UASP CV and DWC_usb3x controller. Thanks!
