1. An apparatus comprising:

  • a transceiver to transmit and receive data between an upstream device and the apparatus;

    service latency reporting logic coupled to the transceiver to determine a latency tolerance value of the apparatus and generate latency tolerance reporting data to report the latency tolerance value to the upstream device, wherein the latency tolerance value comprises a time value of latency corresponding to an activity state of the apparatus and the latency tolerance reporting data identifies the time value;

    wherein the latency tolerance value for an idle activity state is greater than the latency tolerance value for an active activity state.
