Michal Kazioraa75ebc2015-02-10 12:48:44 +010064 * Some APs experience problems when working with U-APSD. Decreasing the
65 * probability of that happening by using legacy mode for all ACs but VO isn't
66 * enough.
67 *
68 * Cisco 4410N originally forced us to enable VO by default only because it
69 * treated non-VO ACs as legacy.
70 *
71 * However some APs (notably Netgear R7000) silently reclassify packets to
72 * different ACs. Since u-APSD ACs require trigger frames for frame retrieval
73 * clients would never see some frames (e.g. ARP responses) or would fetch them
74 * accidentally after a long time.
75 *
76 * It makes little sense to enable u-APSD queues by default because it needs
77 * userspace applications to be aware of it to actually take advantage of the
78 * possible additional powersavings. Implicitly depending on driver autotrigger
79 * frame support doesn't make much sense.
