+PTPIP data types:
+1. request packet & response packet
+2. data packets: start data, data, end data
+3. cancel packet
+4. probe packet and response
+
+The structure as per the MTP type hierarchy is as follows:
+
+One ptpip container of the mtp compound type for the generic use ( it would be 
+used for everything except the data phase commands). This contains the type and 
+length as its first 8 bytes. The next part is the payload, which can be of the 
+following types:
+1. Request type 
+2. Cancel type
+3. Start data type
+ 
+One generic ptpip container of the Mtp compound type for the data phase. This 
+contains the len, type and transaction id as its first 12 bytes. The next part 
+is the payload which is provided by the mtp framework.
