+/* AQ commands based interfaces of i40e_read_rx_ctl() and i40e_write_rx_ctl()
+ * are required for reading/writing below registers, as reading/writing it
+ * directly may not function correctly if the device is under heavy small
+ * packet traffic. Note that those interfaces are available from FVL5 and not
+ * suitable before the AdminQ is ready during initialization.
