Usage
# iwconfig <vap_name> txpower <val_in_dBm>

Note:
Txpower setting can be defined as the minimum value that can be picked from the max regulatory power
settings, from any user defined value and also from the maximum values the radio can support.
So it is not guaranteed that the user defined value gets effected when these settings is done.
