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]).
@param[in] This Pointer to the EFI_MTFTP6_PROTOCOL instance.
@param[in] Token Pointer to the token structure to provide the parameters that are
used in this operation.
@retval EFI_SUCCESS The MTFTPv6 related file "directory" has been downloaded.
@retval EFI_UNSUPPORTED The EFI MTFTPv6 Protocol driver does not support this function.
@retval EFI_INVALID_PARAMETER One or more of the following conditions is TRUE:
- This is NULL.
- Token is NULL.
- Token.Filename is NULL.
- Token.OptionCount is not zero and Token.OptionList is NULL.
- One or more options in Token.OptionList have wrong format.
- Token.Buffer and Token.CheckPacket are both NULL.
- Token.OverrideData.ServerIp is not valid unicast IPv6 addresses.
@retval EFI_UNSUPPORTED One or more options in the Token.OptionList are not
supported by this implementation.
@retval EFI_NOT_STARTED The EFI MTFTPv6 Protocol driver has not been started.
@retval EFI_NO_MAPPING The underlying IPv6 driver was responsible for choosing a source
address for this instance, but no source address was available for use.
@retval EFI_ALREADY_STARTED This Token is already being used in another MTFTPv6 session.
@retval EFI_OUT_OF_RESOURCES Required system resources could not be allocated.
@retval EFI_ACCESS_DENIED The previous operation has not completed yet.
@retval EFI_DEVICE_ERROR An unexpected network error or system error occurred.

/**
Polls for incoming data packets and processes outgoing data packets.
The Poll() function can be used by network drivers and applications to increase the rate that data
packets are moved between the communications device and the transmit and receive queues.
In some systems, the periodic timer event in the managed network driver may not poll the
underlying communications device fast enough to transmit and/or receive all data packets without
missing incoming packets or dropping outgoing packets. Drivers and applications that are
experiencing packet loss should try calling the Poll() function more often.
@param[in] This Pointer to the EFI_MTFTP6_PROTOCOL instance.
@retval EFI_SUCCESS Incoming or outgoing data was processed.
@retval EFI_NOT_STARTED This EFI MTFTPv6 Protocol instance has not been started.
@retval EFI_INVALID_PARAMETER This is NULL.
@retval EFI_DEVICE_ERROR An unexpected system or network error occurred.
@retval EFI_TIMEOUT Data was dropped out of the transmit and/or receive queue.
Consider increasing the polling rate.
