63 | * Some APs experience problems when working with U-APSD. Decreasing the |
64 | * probability of that happening by using legacy mode for all ACs but VO isn't | |
65 | * enough. | |
66 | * | |
67 | * Cisco 4410N originally forced us to enable VO by default only because it | |
68 | * treated non-VO ACs as legacy. | |
69 | * | |
70 | * However some APs (notably Netgear R7000) silently reclassify packets to | |
71 | * different ACs. Since u-APSD ACs require trigger frames for frame retrieval | |
72 | * clients would never see some frames (e.g. ARP responses) or would fetch them | |
73 | * accidentally after a long time. | |
74 | * | |
75 | * It makes little sense to enable u-APSD queues by default because it needs | |
76 | * userspace applications to be aware of it to actually take advantage of the | |
77 | * possible additional powersavings. Implicitly depending on driver autotrigger | |
78 | * frame support doesn't make much sense. | |
