So the SGSN cannot do proper queue control under non-optimal conditions. This commit computes the leak rate for the last flow control interval by computing the maximum theoretical leak rate and basically substracting control blocks, nacked blocks, and reduced block sizes due to CS downgrade. By using this approach, the value will by more stable on low load, where the value will tend to be near the value derived from the configuration. On full load the transmitted value is completely derived from the measurements. Note that the MS default values are no adapted to the adapted BVC leak rate, since a single MS which has a lower link quality would otherwise be reducing the rate of another MS with good radio conditions, which would not make much sense if they did not share any PDCH.
