What: old static regulatory information and ieee80211_regdom module parameter
When: 2.6.29
What: The ieee80211_regdom module parameter
When: March 2010 / desktop catchup
Why: This was inherited by the CONFIG_WIRELESS_OLD_REGULATORY code,
and currently serves as an option for users to define an
ISO / IEC 3166 alpha2 code for the country they are currently
present in. Although there are userspace API replacements for this
through nl80211 distributions haven't yet caught up with implementing
decent alternatives through standard GUIs. Although available as an
option through iw or wpa_supplicant its just a matter of time before
distributions pick up good GUI options for this. The ideal solution
would actually consist of intelligent designs which would do this for
the user automatically even when travelling through different countries.
Until then we leave this module parameter as a compromise.
When userspace improves with reasonable widely-available alternatives for
this we will no longer need this module parameter. This entry hopes that
by the super-futuristically looking date of "March 2010" we will have
such replacements widely available.
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 also kept around the ieee80211_regdom module parameter in case
some applications were relying on it. Changing regulatory domains
can now be done instead by using nl80211, as is done with iw.
set. We will remove this option once the standard Linux desktop catches
up with the new userspace APIs we have implemented.

This is a driver for the Atheros "otus" 802.11n USB devices.
These devices require additional firmware (2 files).
For now, these files can be downloaded from here:
http://wireless.kernel.org/en/users/Drivers/ar9170
If you choose to build a module, it'll be called ar9170usb.
