498	/**
499	Used to perform TFTP and MTFTP services.
500
501	This function is used to perform TFTP and MTFTP services. This includes the
502	TFTP operations to get the size of a file, read a directory, read a file, and
503	write a file. It also includes the MTFTP operations to get the size of a file,
504	read a directory, and read a file. The type of operation is specified by Operation.
505	If the callback function that is invoked during the TFTP/MTFTP operation does
506	not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will
507	be returned.
508	For read operations, the return data will be placed in the buffer specified by
509	BufferPtr. If BufferSize is too small to contain the entire downloaded file,
510	then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero
511	or the size of the requested file (the size of the requested file is only returned
512	if the TFTP server supports TFTP options). If BufferSize is large enough for the
513	read operation, then BufferSize will be set to the size of the downloaded file,
514	and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp() services
515	should use the get-file-size operations to determine the size of the downloaded
516	file prior to using the read-file operations--especially when downloading large
517	(greater than 64 MB) files--instead of making two calls to the read-file operation.
518	Following this recommendation will save time if the file is larger than expected
519	and the TFTP server does not support TFTP option extensions. Without TFTP option
520	extension support, the client has to download the entire file, counting and discarding
521	the received packets, to determine the file size.
522	For write operations, the data to be sent is in the buffer specified by BufferPtr.
523	BufferSize specifies the number of bytes to send. If the write operation completes
524	successfully, then EFI_SUCCESS will be returned.
525	For TFTP "get file size" operations, the size of the requested file or directory
526	is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server
527	does not support options, the file will be downloaded into a bit bucket and the
528	length of the downloaded file will be returned. For MTFTP "get file size" operations,
529	if the MTFTP server does not support the "get file size" option, EFI_UNSUPPORTED
530	will be returned.
531	This function can take up to 10 seconds to timeout and return control to the caller.
532	If the TFTP sequence does not complete, EFI_TIMEOUT will be returned.
533	If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE,
534	then the TFTP sequence is stopped and EFI_ABORTED will be returned.
535	The format of the data returned from a TFTP read directory operation is a null-terminated
536	filename followed by a null-terminated information string, of the form
537	"size year-month-day hour:minute:second" (i.e. %d %d-%d-%d %d:%d:%f - note that
538	the seconds field can be a decimal number), where the date and time are UTC. For
539	an MTFTP read directory command, there is additionally a null-terminated multicast
540	IP address preceding the filename of the form %d.%d.%d.%d for IP v4. The final
541	entry is itself null-terminated, so that the final information string is terminated
542	with two null octets.
