Thanks for the patch! A few comments below.

It looks like 5150-5250 MHz also requires DFS.

5250-5350 and 5470-5725 MHz require TPC. Since Linux does not support
TPC the power limits need to be reduced by 3 dBm, which puts them at 125
mW.

I also don't see any DFS requirement for 5470-5725 MHz.

Thanks,
