Is there way to return BER as rate, or should it be calculated by the application (from total and error bit counts)?

You seems to change value to 64 bit already, which is enough. 32bit is absolutely too small, it will overflow in seconds (practically around 10sec when there is radio channel of 32MHz and quite optimal conditions).

It is 64bit returned to userspace, is it? Does 64bit calculations causes any complexity of Kernel or app space?

Basically, that API is more complex that I would like to see, but I can live with it. I still fear making too complex API causes same problems as we has currently... lack of app support.
