| 27 | * While this file is called 'ioctl' is purpose goes a little beyond |
|---|
| 28 | * that. This file defines the types and contants used to implement |
|---|
| 29 | * the p80211 request/confirm/indicate interfaces on Linux. The |
|---|
| 30 | * request/confirm interface is, in fact, normally implemented as an |
|---|
| 31 | * ioctl. The indicate interface on the other hand, is implemented |
|---|
| 32 | * using the Linux 'netlink' interface. |
|---|
| 33 | * |
|---|
| 34 | * The reason I say that request/confirm is 'normally' implemented |
|---|
| 35 | * via ioctl is that we're reserving the right to be able to send |
|---|
| 36 | * request commands via the netlink interface. This will be necessary |
|---|
| 37 | * if we ever need to send request messages when there aren't any |
|---|
| 38 | * wlan network devices present (i.e. sending a message that only p80211 |
|---|
| 39 | * cares about. |
