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