|
* 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.
