435 | @param HeaderSize The size, in bytes, of the media header received on the network\r | |
436 | interface. If this parameter is NULL, then the media header size\r | |
437 | will not be returned.\r | |
438 | @param BuffSize On entry, the size, in bytes, of Buffer. On exit, the size, in\r | |
439 | bytes, of the packet that was received on the network interface.\r | |
440 | @param Buffer A pointer to the data buffer to receive both the media header and\r | |
441 | the data.\r | |
442 | @param SourceAddr The source HW MAC address. If this parameter is NULL, the\r | |
443 | HW MAC source address will not be extracted from the media\r | |
444 | header.\r | |
445 | @param DestinationAddr The destination HW MAC address. If this parameter is NULL,\r | |
446 | the HW MAC destination address will not be extracted from the\r | |
447 | media header.\r | |
448 | @param Protocol The media header type. If this parameter is NULL, then the\r | |
449 | protocol will not be extracted from the media header. See\r | |
450 | RFC 1700 section "Ether Types" for examples.\r | |
451 | \r | |
452 | @retval EFI_SUCCESS The received data was stored in Buffer, and BufferSize has\r | |
453 | been updated to the number of bytes received.\r | |
454 | @retval EFI_NOT_READY The network interface is too busy to accept this transmit\r | |
455 | request.\r | |
456 | @retval EFI_BUFFER_TOO_SMALL The BufferSize parameter is too small.\r | |
457 | @retval EFI_DEVICE_ERROR The command could not be sent to the network interface.\r | |
458 | @retval EFI_ACCESS_DENIED Error acquire global lock for operation.\r | |
