The current Host AP driver does not support txpower parameter.

How did you measure the default power? The driver does not change this
value and the firmware code is free to select whichever power level it
wants to. In other words, I would actually expect the card to use its
maximum power level unless there is a clear indication (e.g., measured
with an external power meter) that this is not the case.
