Thanks for reporting this.

Stephen do ar9170 cards get sold with a regulatory domain set to 0x8000?
If so we need to deal with this in the common ath.ko module and set the regulatory
domain as intended.

If we are not sure we can simply default to one of the world regulatory domains for
this specific case, 0x64, for example.

Thanks,
