    <!-- Icons for showing tether enable notification.

         Each item should have two elements and be separated with ";".



         The first element is downstream types which is one of tethering. This element has to be

         made by WIFI, USB, BT, and OR'd with the others. Use "|" to combine multiple downstream

         types and use "," to separate each combinations. Such as



             USB|BT,WIFI|USB|BT



         The second element is icon for the item. This element has to be composed by

         <package name>:drawable/<resource name>. Such as



             1. com.android.networkstack.tethering:drawable/stat_sys_tether_general

             2. android:drawable/xxx



         So the entire string of each item would be



             USB|BT,WIFI|USB|BT;com.android.networkstack.tethering:drawable/stat_sys_tether_general



         NOTE: One config can be separated into two or more for readability. Such as

               USB|BT;android:drawable/xxx
