+ * This interface is used by telephony and telecom to talk to cellular radio.
+ * All the functions have minimum one parameter:
+ * serial: which corresponds to serial no. of request. Serial numbers must only be memorized for the
+ * duration of a method call. If clients provide colliding serials (including passing the same
+ * serial to different methods), multiple responses (one for each method call) must still be served.
+ * setResponseFunctions must work with @1.1::IRadioResponse and @1.1::IRadioIndication.

+     * Setup a packet data connection. If DataCallResponse.status returns DataCallFailCause:NONE,
+     * the data connection must be added to data calls and a unsolDataCallListChanged() must be
+     * sent. The call remains until removed by subsequent unsolDataCallIstChanged(). It may be
+     * lost due to many factors, including deactivateDataCall() being issued, the radio powered
+     * off, reception lost or even transient factors like congestion. This data call list is
+     * returned by getDataCallList() and dataCallListChanged().
+     *
+     * The Radio is expected to:
+     *   - Create one data call context.
+     *   - Create and configure a dedicated interface for the context.
+     *   - The interface must be point to point.
+     *   - The interface is configured with one or more addresses and is capable of sending and
+     *     receiving packets. The prefix length of the addresses must be /32 for IPv4 and /128
+     *     for IPv6.
+     *   - Must not modify routing configuration related to this interface; routing management is
+     *     exclusively within the purview of the Android OS.
+     *   - Support simultaneous data call contexts up to DataRegStateResult.maxDataCalls specified
+     *     in the response of getDataRegistrationState.
