This object represents the current value for transmit
power level. This value is sent to the APs that join the
controller. The APs in turn propogate this value to the
802.11 clients. The client will either use this value or
may tune the transmit power settings between the range
of values configured by clrRrmTupleTransmitPowerLevelMin
and clrRrmTupleTransmitPowerLevelMax objects.
