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