What is the max power for my card?

[Sachin Ganu]

Hi Jouni,

On similar lines, everything below -47dBm is clamped.
My question is what is the actual transmit power of the card when
the card is set at -47dBm?

I think there is a routine in prism2_ioctl.c that does the calculation
But I am not sure on what is the actual Tx power of the card?
