+        tristate "Atheros 802.11n wireless cards support"
+        depends on PCI && MAC80211 && WLAN_80211
+        ---help---
+          This module adds support for wireless adapters based on
+          Atheros IEEE 802.11n AR5008 and AR9001 family of chipsets.
+
+          If you choose to build a module, it'll be called ath9k.

+ * Interface definitions for transmit rate control modules for the
+ * Atheros driver.
+ *
+ * A rate control module is responsible for choosing the transmit rate
+ * for each data frame.  Management+control frames are always sent at
+ * a fixed rate.
+ *
+ * Only one module may be present at a time; the driver references
+ * rate control interfaces by symbol name.  If multiple modules are
+ * to be supported we'll need to switch to a registration-based scheme
+ * as is currently done, for example, for authentication modules.
+ *
+ * An instance of the rate control module is attached to each device
+ * at attach time and detached when the device is destroyed.  The module
+ * may associate data with each device and each node (station).  Both
+ * sets of storage are opaque except for the size of the per-node storage
+ * which must be provided when the module is attached.
+ *
+ * The rate control module is notified for each state transition and
+ * station association/reassociation.  Otherwise it is queried for a
+ * rate for each outgoing frame and provided status from each transmitted
+ * frame.  Any ancillary processing is the responsibility of the module
+ * (e.g. if periodic processing is required then the module should setup
+ * it's own timer).
+ *
+ * In addition to the transmit rate for each frame the module must also
+ * indicate the number of attempts to make at the specified rate.  If this
+ * number is != ATH_TXMAXTRY then an additional callback is made to setup
+ * additional transmit state.  The rate control code is assumed to write
+ * this additional data directly to the transmit descriptor.
