That makes it all very difficult, I think that an EU domain is OK
provided that there is also a Spanish domain. Or maybe the EU domain
should actually be named ETSI (which was my original preference, it was
John Linville that said EU hence why I used it).
I think we had ETSI in some of the original proposals and I think that
makes much more sense.
I'll have to see if I can work out what the allowable domains are for
the Ralink RT2500 drivers, under Windows for instance. I know that are
are considerable number of choices, certainly more than US/EU/JP. That
might provide a good clue.
I'm not sure we care that much, we have a huge list somewhere (look for
softmac work in this area from Larry Finger)
Is it in the code?
Does anyone know how the EEPROM contents are supposed to work for the
Intel hardware? How they are queried and compared with kernel and
userspace programs?
The EEPROM is queried once and that's all the channels you saw in your
iw dev wlan0 info output, then userspace restricts it further. The
hardware also assumes you never move out of the country you bought it
in.
The 802.11d stuff is designed to allow an AP to tell you the reg domain
you're in, but I don't know how many implement it. This is included in
the rolled up 802.11-2007 document I think, although it's more difficult
to find. Ah, right, it's there, section 7.2.3.1 details it.
If this is commonly broadcast in AP beacons then I assume we should be
using it, but if the scan is restricted to the FCC allocation then APs
not set to FCC channels will never be found. That suggests the default
reg dom should actually cover all channels the hardware supports.
