Regulatory Framework & rt2x00.

[Gertjan van Wingerde <gwingerde@kpnplanet.nl>]

Hi Luis,

I'm working on making rt2x00 use the regulatory framework to report its 
EEPROM region settings to mac80211, and I have stumbled upon an issue 
that I don't really know how to solve with the current regulatory 
framework code.

The problem I'm facing is that many of the Ralink devices have 2 region 
settings in their EEPROM, one for 802.11a networks, and one for 
802.11[bgn] networks. So far I have only seen devices where these two 
settings contain the same region indication, but I don't know whether 
this is the case for all devices.

At this point in time I use the regulatory_hint function at driver 
start-up time to communicate the region setting that matches the 
configured band, but that would (probably) not hold up when the user 
reconfigures the mode.

So, at this point in time I have the following questions:
1. How would I be able to communicate both these settings to the 
regulatory framework?
2. Should I re-use regulator_hint whenever the configured band changes?
3. Would a driver supplied region override a user configured setting 
(via iw/crda)?

I would appreciate your help in solving this issue.
