Hello!

I know this is the Linux kernel wireless list, and not Android, but due
to the lack of better places, I'm going to ask here...

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

I am trying to make IBSS mode work on Android. As I'm finding problems
with "bcmdhd", I am wondering if using the "brcmfmac" under Android
would be the better way to go?

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.

I succeeded to compile brcmfmac from recent compat-drivers against the
"tuna" (Galaxy Nexus) kernel, the modules load, but no device is
recognized. Has anyone succeeded doing this? Is there any chance it can
work?

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?

Also I'm wondering what is the relation between the "bcmdhd" driver on
Android and "brcmfmac" in the standard Linux kernel. Is there any
official maintainer of "bcmdhd", any place where to submit patches? Will
"bcmdhd" and "brcmfmac" merge eventually?

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.
