Hello,
In the new linux kernels, the older WLEXT is replaced by cfg80211 along with nl80211 for Full-Mac drivers/hardware.
Being new in this arena, trying to develop a SDIO WL driver for a chip running on a ARM-7 based dev platform - can anyone help me with the following?

1. Do I need to write my own cfg80211.c which sits on top of the SDIO WL driver?

2. There are so many APIs in the cfg80211.h - how to decide which one to use? Also, do I develop my own cfg80211.h file as well?

3. How do I call the nl80211 interface via cfg80211.c?

Any help recommendations is very much appreciated.

regards
Roy
