[RFC] Geographical/regulatory information for ieee80211

[Larry Finger <Larry.Finger@lwfinger.net>]

I am planning on writing a new routine to be added to net/ieee80211/ieee80211_geo.c that will 
populate an ieee80211_geo object given a country code. The new routine will eliminate the need for 
each driver to do their own.

Finding the allowable channels, etc. for various countries has not been easy; however, Cisco 
(http://www.cisco.com/en/US/products/ps6305/products_configuration_guide_chapter09186a008059c96f.html) 
has what seems to be the most complete listing of country information. Neglecting any discussion of 
maximum power, I have been able to arrange the countries into the following groups:

Any countries not listed above will be placed in group 9 with b/g channels of 1-11 and no valid "a" 
channels.

Please tell me if I have (a) missed any countries, or (b) gotten them wrong. Once I have a 
"netdev-list approved" set, I will do some coding. I have noticed that not all the ipw2200 codes 
that are listed in Documentation/README.ipw2200 correspond to these groups. All of the differences 
are in the valid "a" channels.

Thanks to Jeff Liebermann (jeffl@comix.santa-cruz.ca.us) for helping me find some of the 
geographical/regulatory info on the Web.
