-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.

+---------------------------
+
+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 driver is for stlc4550 or stlc4560 based wireless chips.
This driver is experimental, untested and will probably only work on
Nokia's N800/N810 Portable Internet Tablet.
If you choose to build a module, it'll be called p54spi.

+ * This command is used both as a command (request to authenticate) and
+ * as an event on the "mlme" multicast group indicating completion of the
+ * authentication process.
+ * When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
+ * interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
+ * BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
+ * the SSID (mainly for association, but is included in authentication
+ * request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
+ * to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
+ * is used to specify the authentication type. %NL80211_ATTR_IE is used to
+ * define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
+ * to be added to the frame.
+ * When used as an event, this reports reception of an Authentication
+ * frame in station and IBSS modes when the local MLME processed the
+ * frame, i.e., it was for the local STA and was received in correct
+ * state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
+ * MLME SAP interface (kernel providing MLME, userspace SME). The
+ * included NL80211_ATTR_FRAME attribute contains the management frame
+ * (including both the header and frame body, but not FCS).
+ * @NL80211_CMD_ASSOCIATE: association request and notification; like
+ * NL80211_CMD_AUTHENTICATE but for Association and Reassociation
+ * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
+ * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
+ * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like

+ * primitives).
+ * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like

---help---
This option enables the old static regulatory information
- and uses it within the new framework. This is available
- temporarily as an option to help prevent immediate issues
- due to the switch to the new regulatory framework which
- does require a new userspace application which has the
- database of regulatory information (CRDA) and another for
- setting regulatory domains (iw).
-
- For more information see:
-
- http://wireless.kernel.org/en/developers/Regulatory/CRDA
- http://wireless.kernel.org/en/users/Documentation/iw
-
- It is important to note though that if you *do* have CRDA present
- and if this option is enabled CRDA *will* be called to update the
- regulatory domain (for US and JP only). Support for letting the user
- set the regulatory domain through iw is also supported. This option
- mainly exists to leave around for a kernel release some old static
- regulatory domains that were defined and to keep around the old
- ieee80211_regdom module parameter. This is being phased out and you
- should stop using them ASAP.
-
- Note: You will need CRDA if you want 802.11d support
-
- Say Y unless you have installed a new userspace application.
- Also say Y if have one currently depending on the ieee80211_regdom
- module parameter and cannot port it to use the new userspace
- interfaces.
