MK		 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.
