└─>Broadcom 43xx SDIO device support (EXPERIMENTAL)
In linux kernel since version 2.6.32 (release Date: 2009-12-02)  
Broadcom 43xx device support for Soft-MAC SDIO devices.

With this config option you can drive Soft-MAC b43 cards with a
Secure Digital I/O interface.
This includes the WLAN daughter card found on the Nintendo Wii
video game console.
Note that this does not support Broadcom 43xx Full-MAC devices.

It's safe to select Y here, even if you don't have a B43 SDIO device.

If unsure, say N.
