How to use android branch ?

[Masashi Honma]

Hello.

I found a new branch on hostap.git tree.

http://hostap.epitest.fi/gitweb/gitweb.cgi?p=hostap.git;a=shortlog;h=refs/heads/android

I could see "ANDROID_BRCM_P2P_PATCH" macro in the branch. So I have thought
the branch could be used as a replacement of external/wpa_supplicant_8
directory in Android source tree.

So I replaced it and I could build it with android-4.0.1_r1 branch. I have wrote
the result of built to Galaxy Nexus. But I could not enable WiFi direct via GUI.

This is a logcat after trying to enable WiFi direct via GUI.

This is a logcat from original android-4.0.1_r1 branch.

My questions are
1. Is the android branch can be used as a replacement of
external/wpa_supplicant_8 directory in Android source tree ?
2. If it can, the android-4.0.1_r1 branch is correct branch ?
