/**
|

|
Download a data file directory from an MTFTPv6 server.
|
||
|
|
||
|
The ReadDirectory() function is used to return a list of files on the
|
||
|
MTFTPv6 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:
|
||
|
- A fixed buffer that is pointed to by Token.Buffer.
|
||
|
- 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.
|
||
|
|
||
|
@param[in] This Pointer to the EFI_MTFTP6_PROTOCOL instance.

used in this operation.

|

|
- 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.
