| 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 |

| 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. |
