42 * - As soon as SW sees the DL NAC error, it should schedule the error handler
43 * - Error handler would sleep for 50ms to see if there are any fatal errors
45 * - If there are fatal errors then SW does normal error recovery.
46 * - If there are no fatal errors then SW sends the NOP command to device
48 * - If NOP command times out, SW does normal error recovery
49 * - If NOP command succeed, skip the error handling.
61 * To workaround this issue, host should set its PA_TACTIVATE time to 1ms even
