*
*  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.
