//-- 动态调整 tx-power under regulatory limit

 

/*

Sets the Tx power for all packets on the device. This power is limited by the regulatory limits encoded into the driver, and

selected by setting the country code (see the iwpriv command setCountry). The value of pwrsetting is provided in units of

dBm. Setting the power_setting value to off will enable the internal power control logic for setting power level. Default Tx

power levels are dependent on information in the selectedregulatory table.
