二、init.freescale.rc
    ......
    service rtw_suppl_con /system/bin/wpa_supplicant          -ip2p0 -Dwext -c /data/misc/wifi/p2p_supplicant.conf -e/data/misc/wifi/entropy.bin -N          -iwlan0 -Dwext -c/data/misc/wifi/wpa_supplicant.conf

         socket wpa_wlan0 dgram 660 wifi wifi
         class main
         disabled
         oneshot
    ......

三、错误：
    1. error1 :
        1. 现象：
            ioctl[SIOCSIWAP]: Operation not permitted
        2. 原因：ctrl_interface指定的路径文件无法生成获取不存在；
        3. 解决方法：
            将/system/etc/wifi/wpa_supplicant.conf里的：
                ctrl_interface=wlan0
            改为：
                ctrl_interface=/data/misc/wifi/sockets

2. error2 :
        1. 现象：

Interactive mode

Could not connect to wpa_supplicant: (null) - re-trying
        2. 原因：
            root@android:/ # wpa_cli -h                                                    
            wpa_cli [-p<path to ctrl sockets>] [-i<ifname>] [-hvB] [-a<action file>]                     [-P<pid file>] [-g<global ctrl>] [-G<ping interval>]  [command..]

              -B = run a daemon in the background
              default path: /data/system/wpa_supplicant     <----------------------
              default interface: first interface found in socket path
        3. 解决方法：
            wpa_cli -i wlan0 -p /data/misc/wifi/sockets

3. error3:
        1. 现象：调试口不断输出：RTL871X: CurIGValue=34, EntryMinUndecoratedSmoothedPWDB = 34
        2. 原因：
            1. drivers/net/wireless/rtl8723bs/hal/rtl8723b/rtl8723b_dm.c
                ......
                void rtl8723b_HalDmWatchDog_in_LPS(IN   PADAPTER    Adapter)
                {
                    ......
                    DBG_871X("CurIGValue=%d, EntryMinUndecoratedSmoothedPWDB = %d\n", pDM_DigTable->CurIGValue, pHalData->EntryMinUndecoratedSmoothedPWDB );
                    ......
                }
            2. drivers/net/wireless/rtl8723bs/include/rtw_debug.h
                #ifdef CONFIG_DEBUG
                #if defined(_dbgdump)

                /*

                 */
                #define CONFIG_DEBUG
        3. 解决办法：
            注释掉#define CONFIG_DEBUG

4. error4:
        1. logcat现象：
            E/WifiStateMachine( 2757): Failed to load driver!
            D/WifiService( 2757): setWifiEnabled: true pid=4175, uid=1000
            E/WifiStateMachine( 2757): DriverFailedState
        2. 原因：
            将wifi驱动作为Linux kernel的内建模块去了，实际上是要做成可插入的模块才行的；
        3. 解决办法：
           编译wifi模块，并放入/system/lib/modules/目录，注意modules目录的权限。

5. error5:
        1. logcat现象：
            ......
            D/WifiHW  ( 2684): Unable to unload driver module "wlan": No such file or directory
            E/WifiStateMachine( 2684): Failed to unload driver!
            E/WifiStateMachine( 2684): DriverFailedState
        2. 原因是：
            root@android:/system/lib/modules # lsmod
            8723bs 1587320 0 - Live 0x00000000
            root@android:/system/lib/modules #
        3. 解决办法
            1. 需要将模块名改为wlan.ko，通过lsmod对应的的模块名，即：wlan.ko。
            2. 将wifi驱动做成Linux内置驱动，然后修改Android层的wifi驱动中insmod、rmmod方法直接return 0:
                hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c
                    static int insmod(const char *filename, const char *args)

                        if (!module)
                            return -1;

ret = init_module(module, size, args);

free(module);

return ret;
                        */

                            if (ret < 0 && errno == EAGAIN)
                                usleep(500000);
                            else
                                break;
                        }

if (ret != 0)
                            ALOGD("Unable to unload driver module \"%s\": %s\n",
                                 modname, strerror(errno));
                        return ret;
                        */
                    }

6. error6:
        1. 现象：
            E/WifiHW  ( 2703): Unable to open connection to supplicant on "/data/system/wpa_supplicant/wlan0": No such file or directory
        2. 解决办法：
            cat hardware/realtek/wlan/libhardware_legacy/wifi
                ......
                // static const char IFACE_DIR[]           = "/data/system/wpa_supplicant";
                static const char IFACE_DIR[]           = "/data/misc/wifi/sockets/";
