I have been trying without success to integrate the Intel 3160 PCI-e module into a Freescale imx.6 based board from BCM Advanced Research running AOSP 4.3 with 3.0.35 kernel and backports 3.14.1. 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:
D/wpa_supplicant( 2565): Initializing interface 'p2p0' conf '/data/misc/wifi/p2p_supplicant.conf' driver 'nl80211' ctrl_interface 'N/A' bridge 'N/A'

I realize some of those drivers are unnecessary (I have an experimenting with various setups).
