  [/StreamCount:{2 | 3}]
        For /Policy:Multistream, this option determines the number of
        sessions.
          2 means two sessions (fast and slow)
          3 means three sessions (slow, medium, fast).

  [/Fallback:{Yes | No}]
        Determines whether clients that are disconnected will continue
        the transfer using another method (if supported by the
        client). If you are using the WDS client, the computer will
        fallback to unicasting.  Wdsmcast.exe does not support a
        fallback mechanism. This option also applies to clients that
        do not support Multistream.  In that case, the computer will
        fall back to another method instead of moving to a slower
        transfer session.

[/TftpMaximumBlockSize:]
        Specifies the maximum block size that the TFTP server can use.

[/EnableTftpVariableWindowExtension:{Yes | No}]
        Specifies if the TFTP variable window extension is enabled.
