In theory, the code to do this already exists: the current way to achieve this is supposed to be to return a status of DID_TIME_OUT to the command, which triggers error recovery. The only difference between this and what you propose is that the eh_timed_out API won't get called (presumably OK since the LLD already knows it wishes to trigger the error handler) and that the error handler will begin at the device reset task management function (again, on the assumption that the LLD cleaned everything up before returning DID_TIME_OUT). Is that sufficient for your purpose or do we really need another API?
