Hi,

Thank you for the patch and sorry for taking so long to get to it.

The database nor Linux supports TPC. Here we can follow FCC 15.407 and
limit the power to under 500mW:

    Transmit power control (TPC). U-NII devices operating in the
    5.25-5.35 GHz band and the 5.47-5.725 GHz band shall employ
    a TPC mechanism. The U-NII device is required to have the
    capability to operate at least 6 dB below the mean EIRP value
    of 30 dBm. A TPC mechanism is not required for systems with
    an e.i.r.p. of less than 500 mW.

This limit is for indoor use only.  The remark column says

    outdoor use is restricted to maximum EIRP of 25 dBm and maximum
    EIRP power spectral density of -2 dBm / MHz

So please add the INDOOR-ONLY flag.

> Note: According to the Telecommunications (Radio-communication) Regulations, 2013 of the Telecommunications Order, 2001 (S 38/2001), "non-localised use" refers to the operations of specified radio-communication equipment or network at a specific frequency or in any specified frequency within the whole of Brunei Darussalam.

Please wrap the commit message to 80 characters per line. This however
doesn't apply to URLs.
