|  | This option turns on the new netlink interface | 
|  | (nl80211) support in cfg80211. | 
|  |  | 
|  | If =n, drivers using mac80211 will be configured via | 
|  | wireless extension support provided by that subsystem. |

|  | ---help--- | 
|  | This option enables the legacy wireless extensions | 
|  | (wireless network interface configuration via ioctls.) | 
|  |  | 
|  | Wireless extensions will be replaced by cfg80211 and | 
|  | will be required only by legacy drivers that implement | 
|  | wireless extension handlers. This option does not | 
|  | affect the wireless-extension backward compatibility | 
|  | code in cfg80211. | 
|  |  | 
|  | Say N (if you can) unless you know you need wireless | 
|  | extensions for external modules. |
