1. A data processing device comprising:
- a controller configured to open a logical channel with another data processing device;
a receiver configured to receive a message from the other data processing device specifying a data link layer protocol data unit size to be used for exchanging data via the logical channel, whereinthe receiver is further configured to receive a data link layer packet data unit from the other data processing device including at least one network layer packet and an unused message part which is at least the indicated data link layer header size and which is arranged within the data link layer packet unit at a position of a data link layer header of the network layer packet; and
a transceiver configured to exchange data with the other data processing device over the logical channel in accordance with the data link layer protocol data unit size wherein the data link layer protocol data unit size is constant for the logical channel until the logical channel is closed.
