So if dynamic power save is enabled, it needs\ncheck the queue the transmitted packet is in and decide if we need to wake\nup or not.\n\nIn a perfect world, where all packets would have correct QoS tags, U-APSD\nenabled queues should not trigger wakeup from power save. But in the real\nworld, where very few packets have correct QoS tags, this won\u0027t work. For\nexample, if only voip class has U-APSD enabled and we send a packet in voip\nclass, but the packets we receive are in best effort class, we would receive\nthe packets with the legacy power save method. And that would increase\nlatencies too much from a voip application point of view.\n\nThe workaround is to enable U-APSD for all qeueus and still use dynamic ps\nwakeup for all other queues except voip. That way we can still save power\nwith a voip application and not sacrifice latency. Normal traffic (in\nbackground, best effort or video class) would still trigger wakeup from\ndynamic power save.\n\nSigned-off-by: Kalle Valo \u003ckalle.valo@nokia.com\u003e\nSigned-off-by: John W.
