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.
