Andreas Eversberg 0c9b50c498 Fix: Handling of final acknowledge on downlink TBFs It is essential to initialize the first_fin_ack variable. Also it is essential not to free TBF, in case the final ack is not received, but all frames have been acked. In this special case, we resend the final block again and again (and poll), until we receive the final ack.		2012-12-18 10:02:58 +01:00
