Info Pointer to the MTFTP information. This information is required to start
or join a multicast TFTP session. It is also required to perform the “get
file size” and “read directory” operations of MTFTP. See “Related
Definitions” below for the description of this data structure.
DontUseBuffer Set to FALSE for normal TFTP and MTFTP read file operation. Setting
this to TRUE will cause TFTP and MTFTP read file operations to
function without a receive buffer, and all of the received packets are
passed to the Callback Protocol which is responsible for storing them.
This field is only used by TFTP and MTFTP read file.
