| 47 | * While this file is called 'ioctl' is purpose goes a little beyond |
| 48 | * that. This file defines the types and contants used to implement |
| 49 | * the p80211 request/confirm/indicate interfaces on Linux. The |
| 50 | * request/confirm interface is, in fact, normally implemented as an |
| 51 | * ioctl. The indicate interface on the other hand, is implemented |
| 52 | * using the Linux 'netlink' interface. |
| 53 | * |
| 54 | * The reason I say that request/confirm is 'normally' implemented |
| 55 | * via ioctl is that we're reserving the right to be able to send |
| 56 | * request commands via the netlink interface. This will be necessary |
| 57 | * if we ever need to send request messages when there aren't any |
| 58 | * wlan network devices present (i.e. sending a message that only p80211 |
| 59 | * cares about. |
