下载android-x86的Framework 和package 两个文件夹；
我们要移植的是android-2.2的版本，所以我们必须得到android-x86在2.2版本上的源码。
mkdir android-x86
cd android-x86
repo init -u git://git.android-x86.org/manifest.git -b froyo-x86
前面初始化了android-x86，接下来你可以repo sync，只需要check out我们需要的几个文件夹，如下：
repo sync platform/build
repo sync platform/frameworks/base
repo sync platform/packages/apps/Settings
下面我们将ethernet部分内容移植到自己的android源码中：
1. 将framework/base/ethernet 复制到源码的framework/base/目录下：
2. 修改源码framework/base目录下的Android.mk
LOCAL_SRC_FILES += \
… \
vpn/java/android/net/vpn/IVpnService.aidl \
185+：ethernet/java/android/net/ethernet/IEthernetManager.aidl
3. 将文件framework/base/service/java/com/android/server/EthernetService.java复制到 framework/base/service/java/com/android/server/目录下；
4. 修改framework/base/service/java/com/android/server目录下的ConnectivityService.java文件：
