Reads the current operational settings.
@param Configure
Initializes, changes, or resets the operational settings for
this instance of the EFI MTFTPv4 Protocol driver.
@param GetInfo
Retrieves information about a file from an MTFTPv4 server.
@param ParseOptions
Parses the options in an MTFTPv4 OACK (options acknowledgement) packet.
@param ReadFile
Downloads a file from an MTFTPv4 server.
@param WriteFile
Uploads a file to an MTFTPv4 server. This function may be unsupported
in some EFI implementations.
@param ReadDirectory
Downloads a related file directory from an MTFTPv4 server. This function
may be unsupported in some EFI implementations.
