You brought it up. And I also want to discuss it. We do want to support
it. But the 3945/4965/5000 hardwares doesn't have the alpha2 information
in their EEPROMs (btw, 2100/2200 does support that). Instead, they have
a band/channel table including freq, tx power, etc in the EEPROM. So a
simple regulatory_hint() API doesn't work. We need a way to export the
channel details to CRDA.

Thanks,
