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.
