Holger Hans Peter Freyther e9b1ebba9d rlc: Test the basic of the gprs_rlc_v_n code for remembering the state 2013-11-26 21:00:51 +01:00
Holger Hans Peter Freyther f1593b7c49 tbf/rlc: Big change and move the window handling out to the rlc 
The send and receive window is now managed by an external object.
There are some issues that can only be solved with C++11 but it
is progres and removes some of the spaghetti code. For GPRS the
sns and ws is hardcoded. Move that into the window code.

Holger Hans Peter Freyther 9a76968ec4 rlc: Use uint16_t for the BSN in all cases. 
The sns is only 128 for GPRS (it can be bigger for EDGE) so the
uint8_t was enough but it is bad to have inconsistencies for both
of them.

Holger Hans Peter Freyther 9c5539d46d tbf/rlc: Move the counting of unacked frames into the RLC V_B class 
Whenwe receive a final ack we assume that all the unacked frames
have been acked now. Move the counting to V_B and now the caller
can remove the BSN and the "lost" variable which has always been
zero.

Holger Hans Peter Freyther bc15570651 tbf/rlc: Change the code and generate the entire state in the V_B 2013-11-26 20:57:24 +01:00
Holger Hans Peter Freyther e358ff8fa4 tbf/rlc: Move the moving of V(A) into the V_B code 
Move the code that moves the V_B to the first not acked frame. Return
how many indexes the V_B was moved and update the V_A in the caller.

Holger Hans Peter Freyther df6b4f52e0 tbf/rlc: Move the parsing of RBB to Decoding, move window marking out 
Move the parsing of the bitbmap out of the TBF code into Decoding.
Move the updating of the V_B into the V_B class. Add some comments
about handling the mod_sns, mod_sns_half parameters by using template
code.

Holger Hans Peter Freyther 1577779526 rlc/tbf: Move the loop into the gprs_rlc_v_b class 2013-11-26 20:57:19 +01:00
Holger Hans Peter Freyther 321f3c3104 rlc: Move the ack state array into a separate class that can be tested 2013-11-23 16:19:17 +01:00
Holger Hans Peter Freyther 58db60c68e rlc: Start to move things out of the tbf into the rlc 
Add remarks of possible broken behavior inside the tbf
routines. Move the preparation (and init) into the new
rlc.cpp file.
