* 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.
