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.

Yes, this detail of information was conveyed to me at OLS by Guy. This
is why we decided to add support for letting the driver not pass an
alpha2 but to just build the regulatory domain structure itself and
pass it. I even provided an example of how to do this in the
Documentation/networking/regulatory.txt and tested it myself.

Essentially this was added with your drivers in mind :)

Let me know if you run into any issues.

Oh and to be clear -- you "can" also pass an alpha2 if you guys do
figure out a way to do that. If not its OK, just set the alpha2 to
NULL.
