The driver loads fines, but is missing the p2p0 netdev required by the wpa supplicant. I subsequently integrated the Johannes Berg Android P2P Workaround Hack patch into backports 3.14.1 and added the iw utility for adding the p2p0 interface. However, the command from that patch thread for adding the interface fails to create the netdev (no error message given, seems to return fine). The logcat still shows the following output related to p2p0, which is probably familiar to some on this list:
can you make sure you have the Kconfig in Johannes's patch set?
can you send the output of iw dev?

This is weird, why do you have iwldvm?
You don't really need it - since Android doesn't have udev, I guess
you just insmoded it?
