+	---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.
+
+	  Say N unless you cannot install a new userspace application
+	  or have one currently depending on the ieee80211_regdom module
+	  parameter and cannot port it to use the new userspace interfaces.
+
+	  This is scheduled for removal for 2.6.29.

- * This regulatory domain control implementation is highly incomplete, it
- * only exists for the purpose of not regressing mac80211.
- *
- * For now, drivers can restrict the set of allowed channels by either
- * not registering those channels or setting the IEEE80211_CHAN_DISABLED
- * flag; that flag will only be *set* by this code, never *cleared.
+/**
+ * DOC: Wireless regulatory infrastructure
  *
  * The usual implementation is for a driver to read a device EEPROM to
  * determine which regulatory domain it should be operating under, then
  * looking up the allowable channels in a driver-local table and finally
  * registering those channels in the wiphy structure.
  *
- * Alternatively, drivers that trust the regulatory domain control here
- * will register a complete set of capabilities and the control code
- * will restrict the set by setting the IEEE80211_CHAN_* flags.
+ * Another set of compliance enforcement is for drivers to use their
+ * own compliance limits which can be stored on the EEPROM. The host
+ * driver or firmware may ensure these are used.
+ *
+ * In addition to all this we provide an extra layer of regulatory
+ * conformance. For drivers which do not have any regulatory
+ * information CRDA provides the complete regulatory solution.
+ * For others it provides a community effort on further restrictions
+ * to enhance compliance.
+ *
+ * Note: When number of rules --> infinity we will not be able to
+ * index on alpha2 any more, instead we'll probably have to
+ * rely on some SHA1 checksum of the regdomain for example.
