标题: RJ45的整个插入检测方法
已经不同模块的通知方法分析

首先，
1）SocketClient检测到RJ45插入信息。

2）这个事件被EthernetMonitor发现。
      public void run() {
         //noinspection InfiniteLoopStatement
         for (;;) {
            int index;
            int i;
            int cmd;
            String dev;

            if (localLOGV) Slog.v(TAG, "zcfdebug go poll events");

            String eventName = EthernetNative.waitForEvent();

            if (eventName == null) {
if (localLOGV) Slog.v(TAG, "zcfdebug no ethernet monitor events");
                  continue;
            }

            if (localLOGV) Slog.v(TAG, "zcfdebug get event " + eventName);

            /*
               * Map event name into event enum
               */
   if (eventName.length()==0) {
EthUeventFail=true;
Slog.v(TAG, "the eventName length is " + eventName.length());
}
            i = 0;

3,然后，通知给Tracker：
mTracker.notifyStateChange(ifname,NetworkInfo.DetailedState.CONNECTED); //zcfdebug++
采用

public void notifyStateChange(String ifname,DetailedState state) {
      Log.e(TAG,"notifyStateChange in EthernetStateTracker!");
      if(state.equals(DetailedState.CONNECTED)){
         Log.e(TAG,"Ethernet connected in EthernetStateTracker!");
      }else
      {
         Log.e(TAG,"Ethernet disconnected in EthernetStateTracker!");
         setState(mHWConnected = false, EVENT_HW_DISCONNECTED); //zcfdebug++20150508
      }
      if (localLOGV) Slog.i(TAG, "zcfdebug report new state " + state.toString() + " on dev " + ifname);
      if (ifname.equals(mInterfaceName)) {
         if (localLOGV) Slog.v(TAG, "zcfdebug update network state tracker");
         synchronized(this) {
            this.sendEmptyMessage(state.equals(DetailedState.CONNECTED)
                  ? EVENT_HW_CONNECTED : EVENT_HW_DISCONNECTED);
         }
      }
}

4,进入
case EVENT_HW_CONNECTED:
            if (localLOGV) Slog.i(TAG, "zcfdebug received HW connected, stack=" + mStackConnected + " HW=" + mHWConnected);
            mHWConnected = true;
            mStackConnected = true; //zcfdebug++
            if (mStackConnected)
                  setState(true, msg.what);
            break;

5，下一步运行到
         case EVENT_HW_PHYCONNECTED:
            if (localLOGV) Slog.i(TAG, "interface up event, kick off connection request");
            if (!mStartingDhcp) {
                  int state = mEM.getState();
                  if (state != mEM.ETHERNET_STATE_DISABLED) {
                     EthernetDevInfo info = mEM.getSavedConfig();
                     if (info != null && mEM.isConfigured()) {
                        try {
                              configureInterface(info);
                        } catch (UnknownHostException e) {
                              // TODO Auto-generated catch block
                              //e.printStackTrace();
                              Slog.e(TAG, "Cannot configure interface");
                        }
                     }
                  }
            }
            break;

6，看看配置
private boolean configureInterface(EthernetDevInfo info) throws UnknownHostException {
DhcpInfo infoDhcp = new DhcpInfo();//zcfdebug++
      mStackConnected = false;
      mHWConnected = false;
      mInterfaceStopped = false;
      mStartingDhcp = true;
NetworkUtils.resetConnections(info.getIfName(), NetworkUtils.RESET_ALL_ADDRESSES);//zcfdebug++
      if (info.getConnectMode().equals(EthernetDevInfo.ETHERNET_CONN_MODE_DHCP)) {
         if (localLOGV) Slog.i(TAG, "trigger dhcp for device " + info.getIfName());
         sDnsPropNames = new String[] {
            "dhcp." + mInterfaceName + ".dns1",
            "dhcp." + mInterfaceName + ".dns2"
         };

         mDhcpTarget.sendEmptyMessage(EVENT_DHCP_START);

关于Tethering部分，后面应该删除：
D/zcfdebug Tethering(  460): interfaceLinkStateChanged eth0, true
D/zcfdebug Tethering(  460): interfaceStatusChanged eth0, true
D/zcfdebug Tethering(  460): Eth0 interface been found
D/zcfdebug Tethering(  460): setLastError: 0
D/zcfdebug Tethering(  460): setLastError: 16
D/zcfdebug Tethering(  460): [ISM_Initial] enter, sendTetherStateChangedBroadcast
