Any particular reason for enabling this? The driver does not 
specifically need it. The option only allows use of WEXT dependent 
user-space tools like iwconfig and iwlist. At least it is not needed by 
brcmfmac driver hence it does not select it.

You indicate there is a dependency. Could you elaborate?
