/**
 * This class defines Message.what base addresses for various protocols that are recognized

 * allows for interaction between different StateMachine implementations without a conflict
 * of message codes.
 *
 * As an example, all messages in {@link android.net.wifi.WifiStateMachine} will have message
 * codes with Message.what starting at Protocol.WIFI + 1 and less than or equal to Protocol.WIFI +
 * Protocol.MAX_MESSAGE
 *
 * NOTE: After a value is created and source released a value shouldn't be changed to
 * maintain backwards compatibility.
