The lines are less drawn than they used to be (at least for me).

I am working mainly on brcmfmac. IBSS should work, but reading the 
commit message of your patch I guess it may be a firmware issue so using 
brcmfmac will not make a difference.

That is how we did it and with success. What do you mean by 'no device 
is recognized'? Do you have any traces to look at?

bcmdhd is what broadcom open-sourced for android. Separately, we started 
working on brcmfmac for the mainline linux kernel. Both drivers come 
from the same proprietary driver. The goal is to have brcmfmac work on 
Android as well and we have most features on board for that.
