Android drive is a little different from brcmfmac. We do have plan to 
add android support on a fullmac based code. But it's not going to 
happen in short time. I would suggest you could start with the android 
driver to save the time of porting fullmac to Android.

No. 11g is supported as well.

We implement the callback and talk to cfg80211 directly.

I don't think there is any interface available to bypass the firmware 
and control the RF directly.

Hope this can help.
