After I modified EEPROM regdom on both cards to 0x36, 'iw reg get' give me
correct regdom name in original configuration, but I spotted strange thing:
When I swaped wifi cards (AR5413 > PCI0, AR5001X+ -> PCI1) I get this:

------------------------------------------------------------------------
Is it a bug, feature or there are sunspots?
In ALL cases changing regdom by 'iw reg set' ISN'T working. Driver/HW actually
ignore changing regdomain.
Can somebody explain me this behavior?
Thanks
