| 37 | * Power save packet queues. There are two queues, one | |
| 38 | * for frames coming from the net80211 layer and the other | |
| 39 | * for frames that come from the driver. Frames from the | |
| 40 | * driver are expected to have M_ENCAP marked to indicate | |
| 41 | * they have already been encapsulated and are treated as | |
| 42 | * higher priority: they are sent first when flushing the | |
| 43 | * queue on a power save state change or in response to a | |
| 44 | * ps-poll frame. | |
| 45 | * | |
| 46 | * Note that frames sent from the high priority queue are | |
| 47 | * fed directly to the driver without going through | |
| 48 | * ieee80211_start again; drivers that send up encap'd | |
| 49 | * frames are required to handle them when they come back. | |
