The WriteFile() function is used to initialize an uploading operation with the
given option list and optionally wait for completion. If one or more of the
options is not supported by the server, the unsupported options are ignored and
a standard TFTP process starts instead. When the upload process completes,
whether successfully or not, Token.Event is signaled, and the EFI MTFTPv4 Protocol
driver updates Token.Status.
The caller can supply the data to be uploaded in the following two modes:
1.Through the user-provided buffer
2.Through a callback function
With the user-provided buffer, the Token.BufferSize field indicates the length
of the buffer, and the driver will upload the data in the buffer. With an
EFI_MTFTP4_PACKET_NEEDED callback function, the driver will call this callback
function to get more data from the user to upload. See the definition of
EFI_MTFTP4_PACKET_NEEDED for more information. These two modes cannot be used at
the same time. The callback function will be ignored if the user provides the buffer.

Downloads a data file "directory" from an MTFTPv4 server.
May be unsupported in some EFI implementations
@param This The MTFTP protocol session
@param Token The user's request wrap token.
The ReadDirectory() function is used to return a list of files on the MTFTPv4
server that are logically (or operationally) related to Token.Filename. The
directory request packet that is sent to the server is built with the option
list that was provided by caller, if present.
The file information that the server returns is put into either of the following
locations:
1.A fixed buffer that is pointed to by Token.Buffer
2.A download service function that is pointed to by Token.CheckPacket
If both Token.Buffer and Token.CheckPacket are used, then Token.CheckPacket will
be called first. If the call is successful, the packet will be stored in Token.Buffer.
The returned directory listing in the Token.Buffer or EFI_MTFTP4_PACKET consists
of a list of two or three variable-length ASCII strings, each terminated by a
null character, for each file in the directory. If the multicast option is involved,
the first field of each directory entry is the static multicast IP address and
UDP port number that is associated with the file name. The format of the field
is ip:ip:ip:ip:port. If the multicast option is not involved, this field and its
terminating null character are not present.
The next field of each directory entry is the file name and the last field is
the file information string. The information string contains the file size and
the create/modify timestamp. The format of the information string is filesize
yyyy-mm-dd hh:mm:ss:ffff. The timestamp is Coordinated Universal Time
(UTC; also known as Greenwich Mean Time [GMT]).
