Major Description
We currently don't support PDU Fragmentation. This is important when requesting a lot of addresses or reading and writing a lot of data, as each packet size cannot exceed the max PDU size. So if the packets exceed the max pdu size, the driver has to automatically fragment the PDU and send the payload in multiple packets. On the reading side fragmented PDUs have to be reassembled. (We could think of completing Futures of individual read requests as they come in)
