That is basically spelling out the PSD restrictions that other regulations
describe in terms of dBm/MHz.

Unfortunately the database format does not support this, so we are limited
to only adding the lowest limit.

Last I asked, the kernel has a PSD field, but it doesn't really do anything
with it. And internally I asked folks working with WiFi to ask our partners,
and they seem to handle PSD restrictions within their firmware.
