* Some APs experience problems when working with U-APSD. Decreasing the |

* probability of that happening by using legacy mode for all ACs but VO isn't |

* enough. |
|
* |
|
* Cisco 4410N originally forced us to enable VO by default only because it |
|
* treated non-VO ACs as legacy. |
|
* |
|
* However some APs (notably Netgear R7000) silently reclassify packets to |
|
* different ACs. Since u-APSD ACs require trigger frames for frame retrieval |
|
* clients would never see some frames (e.g. ARP responses) or would fetch them |
|
* accidentally after a long time. |
|
* |
|
* It makes little sense to enable u-APSD queues by default because it needs |
|
* userspace applications to be aware of it to actually take advantage of the |
|
* possible additional powersavings. Implicitly depending on driver autotrigger |
|
* frame support doesn't make much sense. |
