  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.
