Based on the translation I've read of the document you've linked to as
well as a couple of others, it sounds like the use of these ranges
requires TPC. Since TPC is not supported in Linux, we need to reduce the
max EIRP for these ranges to 20 dBm.

While modifying them, let's also update the 5170-5350 range to 5150-5350
to match the regulations.

Thanks,
Seth
