149 The Configure() function is used to set and change the configuration
150 data for this EFI MTFTPv6 Protocol driver instance. The configuration
151 data can be reset to startup defaults by calling Configure() with
152 MtftpConfigData set to NULL. Whenever the instance is reset, any
153 pending operation is aborted. By changing the EFI MTFTPv6 Protocol
154 driver instance configuration data, the client can connect to
155 different MTFTPv6 servers. The configuration parameters in
156 MtftpConfigData are used as the default parameters in later MTFTPv6
157 operations and can be overridden in later operations.

257 Parse the options in an MTFTPv6 OACK packet.
259 The ParseOptions() function parses the option fields in an MTFTPv6 OACK
260 packet and returns the number of options that were found, and optionally,
261 a list of pointers to the options in the packet. If one or more of the

297 Download a file from an MTFTPv6 server.
299 The ReadFile() function is used to initialize and start an MTFTPv6 download
300 process and optionally wait for completion. When the download operation
301 completes, whether successfully or not, the Token.Status field is updated
302 by the EFI MTFTPv6 Protocol driver, and then Token.Event is signaled if it
304 Data can be downloaded from the MTFTPv6 server into either of the following
306 - A fixed buffer that is pointed to by Token.Buffer.
307 - A download service function that is pointed to by Token.CheckPacket.
308 If both Token.Buffer and Token.CheckPacket are used, then Token.CheckPacket
309 will be called first. If the call is successful, the packet will be stored

344 Send a file to an MTFTPv6 server.
346 The WriteFile() function is used to initialize an uploading operation
347 with the given option list, and optionally, wait for completion. If one
348 or more of the options is not supported by the server, the unsupported
349 options are ignored and a standard TFTP process starts instead. When
350 the upload process completes, whether successfully or not, Token.Event
351 is signaled, and the EFI MTFTPv6 Protocol driver updates Token.Status.
352 The caller can supply the data to be uploaded in the following two modes:
353 - Through the user-provided buffer.
354 - Through a callback function.
355 With the user-provided buffer, the Token.BufferSize field indicates
356 the length of the buffer, and the driver will upload the data in the
357 buffer. With an EFI_MTFTP6_PACKET_NEEDED callback function, the driver
358 will call this callback function to get more data from the user to upload.
360 @param[in] This Pointer to the EFI_MTFTP6_PROTOCOL instance.
361 @param[in] Token Pointer to the token structure to provide the parameters that are
362 used in this operation.

372 - Token.Buffer and Token.PacketNeeded are both NULL.
373 - Token.OverrideData.ServerIp is not valid unicast IPv6 addresses.
374 @retval EFI_UNSUPPORTED One or more options in the Token.OptionList are not
375 supported by this implementation.

393 Download a data file directory from an MTFTPv6 server.
395 The ReadDirectory() function is used to return a list of files on the
396 MTFTPv6 server that are logically (or operationally) related to
397 Token.Filename. The directory request packet that is sent to the server
398 is built with the option list that was provided by caller, if present.
399 The file information that the server returns is put into either of
400 the following locations:
401 - A fixed buffer that is pointed to by Token.Buffer.
402 - A download service function that is pointed to by Token.CheckPacket.
403 If both Token.Buffer and Token.CheckPacket are used, then Token.CheckPacket
404 will be called first. If the call is successful, the packet will be stored
407 @param[in] This Pointer to the EFI_MTFTP6_PROTOCOL instance.

440 Polls for incoming data packets and processes outgoing data packets.
442 The Poll() function can be used by network drivers and applications
443 to increase the rate that data packets are moved between the
444 communications device and the transmit and receive queues.In some
445 systems, the periodic timer event in the managed network driver may
446 not poll the underlying communications device fast enough to transmit
447 and/or receive all data packets without missing incoming packets or
448 dropping outgoing packets. Drivers and applications that are
449 experiencing packet loss should try calling the Poll() function
