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.
