Angelo Athanassopoulos 07abf4329d PSEA - IEI DNN - This is the last IEI in the message. 
Before this commit each time the message was captured, it entered the
default switch statement, which is meant to show that  we received an
uknown IEI.

Now after the DNN IEI, we set offset=msg_length, to exit the
switch.
