+     * 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 apply them
+     * 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.

+     * 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

+     * 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 {@code warningBytes} must always be less than or equal to {@code limitBytes},
