-When:  March 2010 / desktop catchup

-Why:   The old regulatory infrastructure has been replaced with a new one
-       which does not require statically defined regulatory domains. We do
-       not want to keep static regulatory domains in the kernel due to the
-       the dynamic nature of regulatory law and localization. We kept around

-
-               * US
-               * JP
-               * EU
-
-       and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
-       set. We will remove this option once the standard Linux desktop catches
-       up with the new userspace APIs we have implemented.
