+      USB RX packet threshold count. In host mode, this field specifies
+      the space that must be available in the RX FIFO before the core can
+      start the corresponding USB RX transaction (burst).
+      In device mode, this field specifies the space that must be
+      available in the RX FIFO before the core can send ERDY for a
+      flow-controlled endpoint. It is only used for SuperSpeed.
+      The valid values for this field are from 1 to 15. (DWC3 SuperSpeed
+      USB 3.0 Controller Databook)

+    description:
+      Max USB RX burst size. In host mode, this field specifies the
+      Maximum Bulk IN burst the DWC_usb3 core can perform. When the system
+      bus is slower than the USB, RX FIFO can overrun during a long burst.
+      You can program a smaller value to this field to limit the RX burst
+      size that the core can perform. It only applies to SS Bulk,
+      Isochronous, and Interrupt IN endpoints in the host mode.
+      In device mode, this field specifies the NUMP value that is sent in
+      ERDY for an OUT endpoint.

+      This count is valid in both host and device modes. It is only used
