1、写在前面，为什么固定？因为在Android设备未连接网络时，会使用随机mac地址，如果想ota升级，不固定mac地址会导致风险。
2、控制wifi是否为随机mac地址功能的核心代码
frameworks/base/core/res/res/values/config.xml
packages/apps/Settings/src/com/android/settings/wifi/WifiConfigController.java
core/res/res/values/config.xml:751: <bool translatable="false" name="config_wifi_connected_mac_randomization_supported">true</bool>
默认为ture 修改为false
grep一下如果有这几个文件，也需要改为false：
device/google/wahoo/overlay/frameworks/base/core/res/res/values/config.xml:370: <bool name="config_wifi_connected_mac_randomization_supported">true</bool>
device/google/crosshatch/overlay/frameworks/base/core/res/res/values/config.xml:449: <bool name="config_wifi_connected_mac_randomization_supported">true</bool>
device/google/bonito/overlay/frameworks/base/core/res/res/values/config.xml:412: <bool name="config_wifi_connected_mac_randomization_supported">true</bool>
3、在初始化的时候进行修改
diff --git a/packages/apps/Settings/src/com/android/settings/wifi/WifiConfigController.java b/packages/apps/Settings/src/com/android/settings/wifi/WifiConfigController.java
