It is set at 0. The original firmware (which isn't Linux but it seems it's
using a version of ath9k) overrides ir too.
See this extract from the bootlog:
EEPROM : EEP_MAP_DEFAULT !!!!!
Powertable magic: a55a
ar5416CheckEepromDef: Read Magic = 0xA55A
need_swap = True.
EEPROM Endianness is not native.. Changing
regDmn[0] 0
regDmn[1] 1f
change it to 1f1f
[HWLAN] Set HWLAN MAC as LAN MAC ..

It will set a default world regdomain (the most restrictive):
static const struct ieee80211_regdomain *ath_default_world_regdomain(void)
{
/* this is the most restrictive */
return &ath_world_regdom_64;
}
static const struct
ieee80211_regdomain *ath_world_regdomain(struct ath_regulatory *reg)
{
switch (reg->regpair->regDmnEnum) {
case 0x60:
case 0x61:
case 0x62:
return &ath_world_regdom_60_61_62;
case 0x63:
case 0x65:
return &ath_world_regdom_63_65;
case 0x64:
return &ath_world_regdom_64;
case 0x66:
case 0x69:
return &ath_world_regdom_66_69;
case 0x67:
case 0x68:
case 0x6A:
return &ath_world_regdom_67_68_6A;
default:
WARN_ON(1);
return ath_default_world_regdomain();
}
}
But I was asking if it's not acceptable to set the regdomain to Spain or
if it's not acceptable to change it at all.
