@ -88,27 +88,6 @@ Who: Luis R. Rodriguez <lrodriguez@atheros.com>
---------------------------
What: CONFIG_WIRELESS_OLD_REGULATORY - old static regulatory information
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
the old static definitions for the regulatory domains of:
* 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.
Who: Luis R. Rodriguez <lrodriguez@atheros.com>
---------------------------
What: dev->power.power_state
When: July 2007
Why: Broken design for runtime control over driver power states, confusing
