Yes, it works out! Thanks a lot. Now I can control the rate for ACKs and the
rate for data frames in a separate way, just to achieve a behaviour like in
real tests with real cards.

But... I also have tried your modification for a IBSS network (i.e. ad hoc
mode) but it seems that basic rates can't be modified with the same code
(obviously I have changed apDev for staDevs. Maybe you can tell me a way to
adapt the BSS modification to the IBSS case.

Thanks again!
