+     * Android uses this request to make its emergency call instead of using @1.0::IRadio.dial
+     * if the 'address' in the 'dialInfo' field is identified as an emergency number by Android.
+     *
+     * In multi-sim scenario, if the emergency number is from a specific subscription, this radio
+     * request can still be sent out on the other subscription as long as routing is set to
+     * @1.4::EmergencyNumberRouting#EMERGENCY. This radio request will not be sent on an inactive
+     * (PIN/PUK locked) subscription unless both subscriptions are PIN/PUK locked. In this case,
+     * the request will be sent on the primary subscription.
+     *
+     * Some countries or carriers require some emergency numbers that must be handled with normal
+     * call routing if possible or emergency routing. 1) if the 'routing' field is specified as
+     * @1.4::EmergencyNumberRouting#NORMAL, the implementation must try the full radio service to
+     * use normal call routing to handle the call; if service cannot support normal routing, the
+     * implementation must use emergency routing to handle the call. 2) if 'routing' is specified
+     * as @1.4::EmergencyNumberRouting#EMERGENCY, the implementation must use emergency routing to
+     * handle the call. 3) if 'routing' is specified as @1.4::EmergencyNumberRouting#UNKNOWN,
+     * Android does not know how to handle the call.
+     *
+     * If the dialed emergency number does not have a specified emergency service category, the
+     * 'categories' field is set to @1.4::EmergencyServiceCategory#UNSPECIFIED; if the dialed
+     * emergency number does not have specified emergency Uniform Resource Names, the 'urns' field
+     * is set to an empty list. If the underlying technology used to request emergency services
+     * does not support the emergency service category or emergency uniform resource names, the
+     * field 'categories' or 'urns' may be ignored.
+     *
+     * In the scenarios that the 'address' in the 'dialInfo' field has other functions besides the
+     * emergency number function, if the 'hasKnownUserIntentEmergency' field is true, the user's
+     * intent for this dial request is emergency call, and the modem must treat this as an actual
+     * emergency dial; if the 'hasKnownUserIntentEmergency' field is false, Android does not know
+     * user's intent for this call.
+     *
+     * If 'isTesting' is true, this request is for testing purpose, and must not be sent to a real
+     * emergency service; otherwise it's for a real emergency call request.
+     *

+    /**
+     * Instruct hardware to send callbacks after certain number of bytes have been transferred in
+     * either direction on this upstream interface.
+     *
+     * The specified quota bytes must be applied to all traffic on the given upstream interface.
+     * This includes hardware forwarded traffic, software forwarded traffic, and AP-originated
+     * traffic. IPv4 and IPv6 traffic both count towards the same quota. IP headers are included
+     * in the byte count quota, but, link-layer headers are not.
+     *
+     * This API may only be called while offload is occurring on this upstream. The hardware
+     * management process MUST NOT store the values when offload is not started and applies once
+     * offload is started. This is because the quota values would likely become stale over
+     * time and would not reflect any new traffic that has occurred.
+     *
+     * This API replaces {@link @1.0::IOffloadControl::setDataLimit}, the framework would always
+     * calls this API if 1.1 HAL is supported. Otherwise, calls the other one. Thus, no
+     * interaction between the two APIs need to be addressed. However, the hardware implementation
+     * still needs to keep functionality of both in case of shipping with older framework that
+     * doesn't support 1.1 HAL.
+     *
+     * The specified quota bytes MUST replace any previous quotas set by
+     * {@code setDataWarningAndLimit} specified on the same interface. It may be interpreted as
+     * "tell me when either <warningBytes> or <limitBytes> bytes have been transferred
+     * (in either direction), and stop offload when <limitBytes> bytes have been transferred,
+     * starting now and counting from zero on <upstream>."
+     *
+     * Once the {@code warningBytes} is reached, the callback registered in initOffload must be
+     * called with {@code OFFLOAD_WARNING_REACHED} to indicate this event. Once the event fires
+     * for this upstream, no further {@code OFFLOAD_WARNING_REACHED} event will be fired for this
+     * upstream unless this method is called again with the same interface. Note that there is
+     * no need to call initOffload again to resume offload if stopOffload was not called by the
+     * client.
+     *
+     * Similarly, Once the {@code limitBytes} is reached, the callback registered in initOffload
+     * must be called with {@code OFFLOAD_STOPPED_LIMIT_REACHED} to indicate this event. Once
+     * the event fires for this upstream, no further {@code OFFLOAD_STOPPED_LIMIT_REACHED}
+     * event will be fired for this upstream unless this method is called again with the same
+     * interface. However, unlike {@code warningBytes}, when {@code limitBytes} is reached,
+     * all offload must be stopped. If offload is desired again, the hardware management
+     * process must be completely reprogrammed by calling setUpstreamParameters and
+     * addDownstream again.
+     *
+     * Note that when one of the quota bytes is reached, the other one is still considered valid
+     * unless this method is called again with the same interface.
+     *
+     * @param upstream Upstream interface name that quota must apply to.
+     * @param warningBytes The quota of warning, defined as the number of bytes, starting from
+     *                     zero and counting from now.
+     * @param limitBytes The quota of limit, defined as the number of bytes, starting from zero
+     *                   and counting from now.
