+  Receive filters, the station address, the statistics, and the multicast-IP-to-HW\r
+  MAC addresses are not reset by this call. If the network interface was\r
+  successfully reset, then EFI_SUCCESS will be returned. If the driver has not\r
+  been initialized, EFI_DEVICE_ERROR will be returned.\r
